I am not sure what the LS/GS tegs have but my GSR has the double bend...that is what I would choose. I have also driven a GSR with a Skunk2 shifter and shift knob and I could feel a difference between that and my stock GSR shifter. The throws seemed more precise and gave a stronger, more solid feel than the stock GSR shifter/knob.
I plan on getting both too when the funds come in.
