This is just opinion / feeling, but I'd say if you are using a 12v drill @ 12v or near to it, (say no more than a 4S lipo) 30A ESC's x4 is the way to go. What I would personally do is grab 1 or 2 spares, because while I dont think you're going to blow all 4 at once even under extreme circumstances, chances of 1 of them going somewhere somehow is higher, so you want to have spares on hand to cover that during an event. Especially if your delicate wheels are prone to stalling the drills.
So AFAIC your options are:
4x 30A + spare(s)
-- 6x $40 = $240 total With 2 spares (Personally I'd recommend this)
-- 5x $40 = $200 total With 1 spare
OR
4x 85A and take the (lower) risk of not getting a spare = 4x $75 = $300 total
Having said all that I'd still recommend shelving the fancy omni drive train for the time being and just putting together a simple, cheap 2WD robot and practicing with that, refining it until it's reliable, then with your greater experience tackle the omniwheel design later on. If you're anything like I was, I'm wasting my breath here, as this is what I was told as well, but I now believe in it strongly enough to preach it to you, so take from that what you will _________________ <Patrician|Away> what does your robot do, sam
