A couple of notes:

-Like others have said, we find ourselves turning down the window motor couplers in various ways every year. We almost always end up turning down the funny tapered shaft to be straight round, and using a plastic bushing to support the other end of the coupler. We then usually turn down the coupler to allow us to use the smallest size of AM plate sprocket without the chain hitting the coupler, and drill more mounting holes for the sprocket. Specifically, things I would change to make the coupler more generic and useful:
--Change the shaft size to 1/2" or 3/8", possibly keyed or hexed.
--Outer portion of the shaft coupler should be a standard size and straight (not tapered), allowing a team to use a plastic bushing to support that end of the coupler
--Change the bolt pattern to 1.875" #10 6-bolt circle
--Change the outer diameter of the part so you can use the smallest AM sprocket (32t for 25 chain) without turning down the part

-I really like Victors.

Suggestions:
-Move everything except the required electrical components and CIM motors to FIRST Choice. Possibly throw in some of the strange new motors as well, but the 550 and Window motors are good candidates for outsourcing to AM or Banebots, with provisions for every team to get the legal amount via FIRST Choice and buy more from Andy/Banebots.

-Release all software prior to kickoff, via download. With the changes that are made to the library every year, it would be very nice to not have to learn all of them in the days following kickoff, or waste many hours installing LV on all of the team computers after kickoff. Leave out the vision examples if you want, but provide them separately (as a ZIP of just the vision files, not as part of the library or other example code)
