Almost everything you posted is wrong.
Black Flame is an adjustable mix, using Colorant to deepen the shade of Grey to the need at hand. If you were referring to Black Flame N/C (No Colorant) then you should specifically say so, not go on to make a statement that is at best misinformation.
Also, Black Flame X1I, a mix you have no personal experience with, is much darker than BF-N/C. And it is of a higher gain.
And to state that the Carls ALR material "soundly" beats Black Flame (...let alone BFX1I...) is completely false, notwithstanding any lack of real personal observance between the two, or your failing to make note that you were perhaps referring to BF-N/C.
Carls ALR has had more comments alluding to hot spotting, viewing cone limitations, and screen artifacts than it has has glowing accolades. You seem to be willing to grab onto a few posts by a few individuals and use them to make definitive statements while ignoring the posts that are less than receptive, and yet again all while you do not have any degree of personal experience doing some testing of all the referred to applications...you only say you'll "grab" some photos...photos that only come from the previously mentioned few.
Despite how you felt the need to interpret things, Zora simply said the two (DEA- BFX1I) were very similar, he did not say they were exactly alike in shade. Besides that, unless you yourself have viewed both side to side as Zora has, you again should refrain from disputing his opinion and making such defining statements when you really don't know enough about anything concerning either to be able to make such statements.
Lastly, although I cannot be absolutely certain what is was about Zora's post that prompted your response, I suspect it had something to do with his personal "ecstatic" judgement that his current DEA screen was beyond even being compared to his older BW. You have seemed overly quick to refer to a application that is both limited in performance and general acceptance. In truth, only those who do not know of any other choice, or who are convinced by others that BW is somehow worth their consideration based on cost alone, choose it out of hand. Those who have enough knowledge acquired by their own study, or supplied to them by other actual users of SF/BF, seldom settle for such a lessor performing application.
Actual facts...not supposition or conjecture (opinions)
- Neither SF / BF BFX1I have a narrow/er viewing cone than BW, certainly not enough to matter to anyone who is seated within the confining walls of any room.
- None of the (directly) above have the reputed "edge dimming" you continually allude to them having. That trait is reserved for the applications that do not share the formulations the aforementioned have.
You continually seem determined to dress down both the potential and performance of SF / BF / BFX1I, choosing either cost, imagined lack of performance differences with other applications, of simplicity of build, when in fact each of those concerns and considerations have been addressed, and anyone who has an interest receives far more help and assistance in dealing with all such things of that nature than they do from any other source.
It's time you started refraining from using the "price" club to try to sway people away from well proven, higher performing applications. It is one thing to state that one cost more than another. It is entirely different when one uses language that purports to say that the price difference is not worth it. If someone ventures to say they do not / cannot afford anything more than a Roller and a can of tinted paint, then yes...they need to be shown what is available. However you do not find anyone, let alone myself trying to persuade them otherwise.
..unless they are getting poor advice that is leading them down a road where they are bound to be disappointed. Only then do I speak up. And it is to be noted that as far as disappointment goes, that seldom..if indeed hardly ever applies to those who do choose SF / BF / BFX1I. And DEA-Flex has been striving to create a product that goes so far as to eliminate every caveat all other such screens exhibit, so in that regard, it to is a cut above the rest and well worth the additional effort and expense.
more to go.........
