I�m doing the same build, open hand monk 6 / thief rogue 4 / fighter 2.
The STR seems a bit of a waste to me. My character has two uses of Misty Step from gear, so she can get to where she needs to be without jumping. Better Con provides survivability and Wis allows me to apply stunning strike reliably, which is amazing against dangerous enemies.
Giving up that to jump far doesn�t seem worth it to me.
