I'm also not opposed to going 10 speed if I would have less clearance issues.

I have searched and wasn't finding satisfactory answers. Any info is appreciated.


Edit:
I found an article that explains my conundrum. I will probably just go with 10 speed.
11 and 12 speed HG MTB cassettes should work.
Chainline should be OK with middle ring.

Note that a new NW chainring would help to keep the chain on. So measure BCD of that middle ring.
