schulze 18.97 on 5s, what motor

[_paralyzed_]

I've narrowed it down to either a kb45 8l 2200kv or a medusa research 36-60 2000kv. Now, then schulze is made for 4 and 6 pole plettys, and the timing is set up for that. The medusa is a 4 pole, and is rated for 900 watts. The kb is a 2 poler and rated well over 2000 watts. Given the schulzes combustible reputation, am I better running a lower watt load? Should I care about the pole count? Batteries will be 2x zippy 5s 5000mah in parallel for 10,000mah.
