Just whatever you do, dont get a unit with the ball-bearing design on a central pivot point....unless you live in Cali. If you live anywhere with normal weather, these shifters will last you 6 months, tops....doesn't matter if it's an APC for $20, or an Edlebrock for $190, like mine that just bit the big one.
The bearings they use are an open design, meaning that over time, dirt, salt, ect... get into those bearings and seize them. When you shift, it feels like there is sand in your shifter....that's because there probably is. Nothing much you can do about it either...other than replace the bearings, or clean them out, reassemble them and cover them in white lithium grease...until a few months down the road it does it again.
So my advice, if you live in Cali or Texas or whatever southern state, go get whatever you want...it'll last. If you live in the North, then Short shifters, for the most part, are for the birds.
I'd say to go with the stock shifter from a GSR. It has one bend and is pretty cool for a stock shifter.
