Why did you choose colsons for your intake over Banebot T40’s or another softer wheel? For an offseason project we built an intake and found that colsons would shred and require significantly more pressure than T40’s to suck in totes.
We already had the colsons, and by the time we thought to switch the BB were out of stock. They are also running on dead axles and we only owned 4 orange BB wheels broached for 1/2" hex, so it was easier to just press a colson dead hub from Vex in there.
We did not experience shredding issues, but we did clean them off with alcohol after a match to keep them tacky.
In the end, if I had time to pick a modification, I would make the intake shorter rather than swap out the wheels. Totes would consistently jam due to the distance between the wheels.
