What would you like to know? I have both a Microperfed Grayhawk RS and StudioTek 130. The two skins are 72" wide 1.78:1 AR, for my Luxus Deluxe frame (this is my reference screen setup, very similar to what Runco uses for their CSMS measurements).
The issue of Microperf and moire isn't cut-and-dry, it depends not only on the projector/technology, but also on the throw distance and screen size. While reviewing the Sony HS-51, I was able to minimize the moire on the screen- but never eliminate it (I had to zoom the image to greater than 100" diag.) Even some DLPs exhibit moire with Microperf, it's not very common for most screen sizes though (92" to 123").
I have yet to see an AT screen that does equally well for both audio and video, the perforated vinyl screens don't do as well with audio, the woven fabric screens have their own video isssues- you really have to pick where you're willing to compromise. Being a Screen Research dealer, I feel that their woven-technology does very well with audio, and I can use their product for very specific applications: when I need an AT screen with an LCD projector without moire. Vutec's soundscreen appears very similar to SR product. I have no experience with Draper's woven product, or with Dalite's perfed product.
The drawback to woven screens is that there IS a visible weave pattern on the screen, it depends on where you're viewing from (distance and angle)- but it is visible. Perfed screens have a similar issue- once you get to within 1X screen width, you begin to notice the holes (depends on screen size, on a tiny screen like mine it could be the reason).
For a long-and-short-of-it answer, I use Stewart- I feel that at this point in time they still make the best screens overall, and offer the most versatility through their product range.
(BTW, I am NOT a Stewart dealer.)
I hope this helps.
