You can use bow string wax on your tip as well as tape it seals the tips and help keep it tite. When tuning your bow do it at 5yds. with out the string on the arrowmake sure its going in the target straight if it goes nochigh move your noc set down. and up if low if your useing a recurve and goes left or rt. you shim or file a little on the riser.The other thing that can cause bad flite is your release. You mite want to play with that . try shooting twounder the arrow. the less fingers we have on the string usallly the better arrow flite. One other thing is arrow length on my own set up anOnsprey at 35# 50% let offI cut 2 inches off the arrow makes it stiffer and really helped the arrow flite. Hope this helps Fred@F&D
