Myself, Butch, and Cootie used the new roller triggers this past weekend.
I realy like the trigger, It seams like it will take a little getting used to. It is a bit different to shoot but with a little practice you can really get the gun rocking.
I'll have Scooter take and post some pics here of the trigger with the wheel that I made.
I haven't had a chance to make and play around with some larger wheels yet.
