I imagine this comes up alot, but I couldn't find a definative answer. I am installing a Marantz 12S1 (their new 16X9 single-DLP model) and a 100" screen in a multi-purpose room where I can control the light pretty well but not to blackout. The main seating position is 13 feet away dead on, but others will sit 10 feet away 30 degrees off center. Which screen do you recommend? From the specs and some discussions with (less than knowledgeable) sales guys, it looks like a tradeoff between gain and off-axis viewing. Is that correct? Also, whats the relative price delta (i.e. firehawk is X times greyhawk). Thanks, great forum.
