Our Off-Season prototype used 4"x2" Colsons although we made our inserts from AL Rod and pressed them in... using a vice of all things. Seems like the big reason that many teams shy away from Colson wheels is the lack of an 'easy' way to make them work with normal FRC drivetrains. I hope they work well for you, that drivetrain looks like a mean one.
