I am hitting the instance cap much faster post-patch thanks to the increased DPS my prot pally does.

I have typically done the following (alliance Prot Pally in Kara-level gear):
10-15 DM
15-20 Stocks
20-40/45 SM: Cath
4-45 (optional) ZF -- I find SM Cath to be "easier" in that I can do it with my eyes closed almost. So I try to stick with cath. Less travel.
45-60 Strat

I have done this pre-RAF and didn't gouge my eyes out. Now that I'm spoiled on RAF, I wouldn't do it without.
