Check out the new xtr shifter, i have been running one for a few weeks. You can push it sram style or index finger it like normal. It can also push 2 gears in either direction and has the adjustable location feature.I agree, downshifting while breaking in a corner is super fun. This is one of the reasons that I run Sram shifters (all shifting with the thumb), I just have not found a place on an 11-32 where I feel like I cannot find the 'right gear'....
