I'm running the both the forge short shifters. One of the best mods in my opinion to. Take into consideration that if you've got the plastic side-to-side shifter arm then you may also need to get the adjustable shifter due to clearance issues (I think, was well over a year ago I had mine so I can't remember the exact reasons), but even if you have the metal arm, I'd still get it as it still improves it further.
