Re: Plaction wheel shooter?

We would like to use the plaction wheels, but I'm afraid that they won't work as well as pneumatic wheels, and we won't be able to test for a few more days.

So... has anyone seen, used, tested or heard of an 8" plaction wheel shooter?
I'd like to try and gain some 2nd hand experience here in order to make the better decision early on.

Thanks,

My team has done extensive prototyping in shooters this year. Although we haven't prototyped an 8 inch plaction wheel shooter we have messed around with other 6-8 inch "hard" (non-pneumatic) wheels. Through our observations it seems that you have to have some sort of give in the system (other than in the frisbee). When using pneumatic wheels the give is in the wheel. When using harder wheels you have to have give in the wall opposite your shooter. My team achieved this using a strip of pool noodle cut to a rectanglar cross-section of about 3/8 x 2 inches.
