When people are satisfied, more often than not they do fade away to simply enjoy the fruits of their labors. For many, asking for help was the hardest part. Sticking around to relate experience when one is already happy is a personal decision that has no bearing on the degree of satisfaction that involves. It should be assumed that they are more pleased than displeased.
When people are NOT satisfied they rend to express such, especially if they feel the need to warn others about the mistake (...or errors...) they made.
When people are indecisive, the root cause is almost always the worry that they might fall into the latter category .
So they want positive assurance that won't be the case in their case..Certainly it would be great if there could be definitive long lists of happy / unhappy End users, but any such request to see such a list is dependent on timing...the effort required to dredge up such info.....and chance.
Someone can always ignore the obvious pros in favor of the unknown "cons" ...but usually that means not going forward. That itself can seem safer...if not indeed self depreciating. But people have been playing it safe to avoid disappointment for as longs there have been....well, people.
I suggested you paint over your BOC, so concern about substrate expense is not an issue. I've done it. Many others have as well. It needs to be done right though.
It would seem that concern about simply going to the relatively small expense, time & trouble of even doing that is more the issue than any real concerns about performance gains.
People who have had years of experience are set to make specific suggestions that carry the weight of the probability of success that far outstrips the potential for failure. There is no motive for suggesting that anyone get involved with suggesting a erroneous choice of action. That would be self destructive.
RS-MaxxMudd has been around now for over 7 years, and if it had anything less than a 95% rate of leaving people satisfied, it would have been shouted down long, long ago. a point in fact is that a few have tried to do that, claiming that the use of metallic content (Mica specifically) is not just unnecessary...it's just plain wrong! Strange though how those same people seem to embrace it's use after they actually get down off the Soapbox and actually start trying it's use on full sized screens.
That the majority of those who are happy do not come back (...or stick around...) to give other undecided souls assurance is pretty normal. However some do embrace the mantra that giving back means as much as receiving. Even so, there will never be the numbers present at one time to give someone absolute 100% assurance they will meet with the end results they want...primarily because everyone has different needs and expectations. Some might even have an ulterior motive they themselves do not as of yet realize to want something to be less than expected...or claimed. That too seems self defeating, but sadly...it's happened before...as would be expected when many hundreds get involved in doing any one thing. The very nature of the Internet tends to root out such folks. Sadly for some, they get into doing things with more of a determination to fail than succeed...because to them the probability of failure always seems greater than that of obtaining a successful end.
So in the end, making a decision is really just a individual choice. If one cannot make the choice based on what known facts are available from stated testimonials, nor use facts and supposition together to create justification, lamenting about how they cannot find absolute guarantees of success given by enough others to make them feel confident is something they alone must deal with.
Bluntly put....someone can use all the tests, graphs, subjective examples and conflicting personal & professional opinions one can find out there all tossed together and still might not reason it all out enough to be assured enough to go forward. DIY Screens is not a Slaughterhouse where we feel the need to goad someone through a chute with a Electric Prod. Instead we try to feed them with as many tasty tidbits as possible, hoping the desire to get to the main course is developed, and if any further encouragement is needed then we let those who have come away feeling sated do all the "prodding".
One could make the argument that if anyone / everyone didn't go to the trouble to do comparative examples of "Before / After" or "Side by Side", then they shouldn't bother trying to exclaim that what they have accomplished really amounted to much of anything. Then again, when people have done exactly that, there are always those waiting in the wings to discount or disprove the effort. I've shown many times such examples....they are out there in my Thread listings. White vs Gray vs Metallic Gray. The end results are always the same.
Honestly.....for anyone to even begin to reason that BOC would be comparable to a higher gain, higher contrast surface is something that speaks of a lack of any real understanding of the basic principles behind Screen performance as relates to Room / PJ considerations. At the price point finding out for one's self entails, if price is the determining factor alone (...as seem to be the case here...) then not much can be done to make that go away. DIY'ing still equates to being more "Bang for the Buck" than any comparably priced Mfg Screen option. But end results are commensurate to, and directly tied to the effort and expense applied.
In the end, if your uncertain...and you are loathe to take the advice of others to breast and make your own effort to prove / disprove such advice, it's not reasonable to expect that anyone else go to extremes to try to convince you otherwise. YOU have to chose, not have the choice fostered off on you....or expect it to be proven beyond all doubt. History and experience shows that when such happens, the scales are weighted toward the "Do'er'" to try find something wrong...simply because they are more interested or concerned about not being satisfied than being satisfied. They might not realize that...but it's more often the case than not.
Of course the last statement falls into the same realm of believability as does all the rest of everything else mentioned or alluded to in this Thread. You have to decide to believe or not based on the source and probability that what is conveyed is true or not. So....were do you go from here?
I might suggest that you yourself go to the effort to do up another Screen...or screens, and do the testing and comparisons you'd like to see provided. You have a BOC Screen waiting. That means you have the chance to provide what you could claim as being definitive results. (...that does take time and money though....)
Why...you might become a Giant in the eyes of fellow DIY'ers.....the stuff DIY legends are made of.
(...I'd pass on that last part iffin; I were you...
