I think that my statement was really pretty clear about it's intended meaning. I certainly wasn't stating it was in any way unfair, misunderstood, or incorrect.....just too narrowly defining and limited in scope to be conclusive. Why stop there...the masses clamor for more.
You obviously have the tools and the talent, so why not simply request the needed "samples" from Spandex World yourself? It would be very much a credit and accomplishment that would be appreciated for quite some time by a very many people on the Forum. Quite frankly, it would probably result in this becoming an Iconic Thread.
Being able to equal or surpass the more expensive Mfg Screens with ultra low cost DIY alternatives is a DIY Screen Forum mandate. Spandex is a classic example in that regard and obvious in it's potential use. In both an aural and visual sense, it can become the essential "Turn To" for a bunch of goodly folk who can design in a "Through the Screen Sound Stage". It's obvious when dealing with a Silver color, that the degree of reflectivity is tied to the openness of the weave. Light loss is a very big issue with many AT screens, and those that do have gains above 1.0 usually suffer from Morie.
Moleskin has had all the Press, and yes I've used and suggested it. And I tried a normal "Silver" in the Milliskin and myself found the attenuation to severe to my tastes
(...I am NOT an advocate of 0.85 Gain using anything....) A real shame that, seeing the latter owes nothing to coated or non-coated Cloth Screen materials, woven or perforated as far as smoothness and a total lack of Morie. I can say that only the very finest of HVLP applied coatings compare, and I do so love my HVLP. Seems that somehow the "Light Silver Matte Milliskin got left in the Moleskin's wake.
However IMO the Light Silver Milliskin takes visual perfection to the next level. Ultra smooth, brighter matte Silver, and great stretchability without visually distorting the nearly invisible surface weave. (...as viewed from under 6 inches...) http://spandexworld.com/c3/catalog/product/5954
4-Way Stretch w 20% Spandex. all that.................and Cheaper too!
To me...the visual aspect is even more important. Many, many more people have expressed a desire to have a ultra lightweight screen to simply hang on the wall. That too has been / is a basic DIY tradition. BOC screens can, when coated, be exceptional. But the needed Frame for a 135" diagonal BOC screen is anything but lightweight. Do a 120" Spandex screen and weight tops out at 20 - 25 lbs
The right Spandex can deliver great, easier results for so many various people it's.....well, it hold great promise. And I commend your work for both it's intent and accomplishment. It's just to get to "The Truth", a few more objective samples need to be included. I sincerely hope you get inundated by enough contributions to outfit a Ski team.
....and post up an impressive test.
