I would much rather have a nice drive and weaker weapon than Vice Versa.
This. I had the same dilemma with Kaizen in so much as I could use either the 500W motors for the drive and have a weaker CIM motor drive the weapon or have the CIM motors doing the driving (which would have meant I could have had it rolling by now) and use one of the 500W motors for the weapon.

This list looks good, just gotta get it built now?
