In general, the GS is for tighter drivetrainss (it supposedly has a tighter
range) and it is supposed to shift more crisply. For some reason it
sometimes is priced higher than the longer SGS model.
Given my druthers, I'd hunt for a M750 derailleur if you're using rapidfire
shifters. The 760 has a reversed spring mech (pushing the derailleur up
onto larger cogs rather than pulling it down to smaller ones.) Currently
this is referred to as "Low Normal" though in the past it was called "Rapid
Rise." It's intended to work best with the new integrated shift/brake
levers. Stockpiles of the older, conventional design are starting to dry
up, but they work better with the older type shifters.
