there is a standard din table used in all ski shops, that takes into account your height, weight, skier type, and boot sole length (mm) like you mentioned. however, this is meant for the general skiing public, which means the dins are usually too low for guys who are charging it. in that case, just bump up the din by 1/2 or 1, and see if your skis stay on when you need them to. but no, there is only the one din table, not a pow specicfic one.
