Ive ben told on glass bows CA glue (AKA super glue),or smooth on for tips.lots of guys seem to be using ca glue.Ive used CA and Urac for wood bows.Some people use Tight Bond wood glue.It depends what your bow is made of i guess.For string length,measure your bow,I think its 3" shorter for long bow and 4" shorter for recurve.Scott
