First, let's agree on some definitions. Throw is the distance from the front of the projector lens to the screen. The distance from the viewer's eyes to the screen is called Viewing Distance. The issue here is how far back is your projector. Does it meet the minimum throw distance for the G3?
The minimum throw distance has to do with noticeable hot spotting on angular reflective screens. If the throw is too short for the screen, the center of the picture will be noticeably brighter than the outsides. Having said that, I would venture to guess that if you do not have noticeable hot spotting with your first gen FH, you probably won't with the G3 either.
