As soon as my drill is fully charged I'm going to be opening up my masking system going from 42" high to 44". My DIY screen is limited at 104" wide, and since I created the masking frame specifically to accommodate 2.35/2.4:1 content, 44" is going to be as tall as I can go without making a new screen.
The nice thing about DIY though, is I only have $40 or so invested in the one I have, so making up a new, bigger one isn't going to bust my budget. And the masking system I have over it can be modified with just a couple hours work.
I remember it wasn't that many years ago when people like Guy Kuo were singing the praises of going a little smaller than average to tighten up the image. Since 1080p and HD players, you sure don't hear that P.O.V. expressed much anymore.
