I'm curious about what other teams are using for rollers on their intake system for 2014.
I'm primarily interested in custom made rollers and what has worked best for controlling the canvased game ball. (Any experience from 2008 is also welcome).
So here are my questions.

What type of roller material are you using?
Was it expensive?
How are you driving it?
Are you using some type of traction material on it?
If so, what type?
Are you using polly cord?
If so how are you controlling the pollycord? (Lathing grooves, building up area around the cord)
Are you using wheels?
If so what type of wheels?

Thanks in advance!
