Wun, speaking as someone close to your size (23.5 mondo boot, 125lb), unless you've got an abnormally short torso, you'll at least want the option to easily cant. The inner mounting holes on many boards are not designed for the inseams of very short guys, and canting gave me more leverage, less leg burn, and a much easier ride. You might want to try flat and canted bindings before you buy, as some require you to buy cant plates as an additional item or as a substitute for flat plates.
