I have been shooting Gametracker 3D select 300s arrows. They shoot great but they do not hold up very long. If another arrow hits the nock of another arrow, the nock end of the gametracker splits or cracks and the arrow is no longer any good, also if another arrow hits or slides down the side of the gametracker, they seem to splinter or crack very easily. I am thinking of going to Gold Tips 3D pros in 55/70, how do they hold up? Thanks!
