they are cam and a half systems.

i bought a new highlander in mid/late july. put about 3000 arrows through it and the string is pretty rough...waxed almost every time i shot...but i guess the days i put a couple hundred arrows through i should almost waxed during the shooting...but still i wasnt impressed with string life...

contact "gibblet" he is our custom string maker on the board...heard hes priced reasonable and makes good strings. i will most likely get mine from him.
