RX8 or MMM combo?

I do like that they make lower KV motors for them, I'd like to run 5s in it sooner or later and that would push the 2650 too far.

I've been tossing around the idea of MMM vs RX8 for a while now and here's what I've come up with:

-I plan on running 6s and there isn't a MMM motor that fits this application. So I either need a Neu, which is going to drive up the cost (to well over the cost of an RX8). Or I need a Medusa which isn't an ideal off-road solution due to the open can and non-captured end bells. The RX8 has a great selection of KVs (even if they seem to be a bit underrated by a variable amount of KV depending on who you ask).

-MMM includes the castleLink and RX8 requires that I pay an additional $35 for hotwire which, honestly I feel is a bit of "nickle and dime" for an already $340 system.

-There are tons of MMMs out there but there are also lots of failures. There aren't a lot of RX8s out there but I haven't heard of one failing yet.

-Sensored vs. sensorless: All of my systems have been sensorless and they perform great. I have tried my friends sensored Novak on his 18T and while I do notice the smoothness in the throttle it doesn't add up to anything in our street races. On the other hand, I feel it's better to have it then to not have it.

What is pushing me toward the RX8 is really the motor selection. I don't feel like hunting down and then paying for a Neu with a bolted can. And 2200kv is just way too much for 6s. And until I hear about an RX8 going up in smoke I consider it the more reliable system (just give it a month...).
