You don't particularly need 6650, unless you want everything to match. Any compact chainset will do, but it would be easier if you kept it Shamino Hollowtech 2 so you don't have to change the BB.
That was the plan, just a little "tick" for me - make sure everything matches (I know, I know haha). ;-)
