i got loads of overlap and i got no troubles trackstanding as long as i want. its only when i drink waaaaay to much coffee and get all jittery that i worry about the overlap because i have to move the wheel the wrong way, but in those cases i should just know better and pull my foot out.
when i first got my cages and not used to having so much overlap i was weaving through pedestrians going pretty slow and i wound up getting my toe stuck against the wheel and flippin right over. thats about as stupid as one can look in front of a crowd of people. everytime i think im an badass on my black ninja bike i do stupid sh@t like that. it keeps me nice and humble.
