We are trying to prepare for next season by learning as much as we can.

We are going to try to modify our shooter by using CIMulator instead of a CIM motor direct to the hub.

Hm if you guys have the machining to do so I would definitely look at designing and building a custom gear box. We used the CIMCIM parts but in a package that was more suited to fit onto our robot. It wasn't a lot of work and came out nice.

CIM-ulator ----- 8mm AM hub ----- directly to wheel???

Depends on your mounting solution I suppose. The CIM-u-lators have two bearings supporting the output shaft, so they're fairly robust. We have one CIM-u-lator on each side of the wheel and haven't had any problems. Full disclosure: we only attended one regional this year, so I can't comment on how it might hold up during an extended season, but we've had a good amount of out-of-competition drive time, both during and after the season.

I would definitely want to otherwise support the shaft if it's being driven directly from a motor, though.

the wheels attach to the hubs and go on the shafts

This is our current setup with the exception of the sprocket setup in the first picture
