well u dont really need a special strp just as long as it can slide on ur shirt.......get the strap locks that slide on they're better for the throw....some guitars arent the best for throwing......like my 2 gibson sg's are not easily capable of throwing b/c of the placement of the bolts.......if it attaches to the arm of the guitar that is best.......oh and when you're starting to do it make sure i wear a collar or you're going to get a big burn on your neck......throwing ur guitar is soemthing you cant really practice.....its better if u do it a couple times before performing but its oen of those things you just have to do w/o thinking
