So I am upgrading to the SLX 2x9 crank and I was also going to purchase a new rear derailleur at the same time. But should I get a med cage x.9 or the long cage. I did the math from the http://forums.mtbr.com/showthread.php?t=284688 which is 37T but I was wondering if anyone is running a similar setup and which one would be best to use. Any Pros, any Cons, anything to lookout for.
Setup: Will be SLX 2x9 at 36-22 t and a 11-34 T cassette
Thanx in advance for any help.
