to be honest the extra straps are no good, you should invest in some strong elasticated velcro strap and put them around the knee pad and behind your knee, you must pack your knee using the knee pad, this will stop your problem, pro jump knee/shin pad are great for this, we use them al the time, also have the knee bar set to your leg size and ballance your pjs, this will give you more performanc and safer jumping, i strongly recomend anyone taping your springs to think of safety, for safety reasons we dont do this,it may look cool but you must always be able to inspect your spring, if anyoneneeds more info on this please ask as i dont want to sound borin, chears.
