I'll talk with marker to see if I can get you a pair of 24 dins but I don't know if they make them that low. Lowest I"ve ever seen is a 36. I"ve personally got the 69din model
if ur actually good enough to do straight airs, then i would suggest getting your boots riveted to your skis, it might be kinda wierd walking around, but atleast your skis shouldnt come off
FUCK bindings AND boots i got magnesium rods incerted in my legs and i simply WELD my leg directly onto my ski wich i MACHINED directly ouf of a 3 ton bock of stainless STEEL for TERMINAL ski to leg grip ratio....
