A lot of teams ran cantilevered wheels off of Toughbox Nanos last year which are made of the same stuff. This could save you a little weight and a lot of strength considering how aggressive your pocketing is around the bearing blocks.
I don't understand that part. We use sliding blocks in 1/8", what would the issue be?

In fact, we use 1/8" purely because of the sliding blocks, and it's usually the only 1/8" on our robot!
