I think SM is a pretty cool guy, eh builds unicycle-bots and doesn't afraid of anything
I think 2WD NPCF with Technos is better and lighter.
Anyway, with 4WD NPCF it is advantageous to use the Trov Chassis glitch.
Go for 5 30kg sledges and see what happens.
Romeo doesn't need a wedge (especially at that speeds).I have doubts on Phantasy's efficiency (it does look totally awesome, though), the LW has greatly improved, and Cantarella's the best of the bunch.
