I' m using Gold Tips and I' m shooting the best I' ve ever shot. They last alot longer too. I' m not adding weight except for the broadhead. I' m shooting 3355' s full length with a 160 gr. eskimo out of a 50# 27 1/2 draw. (348gr.) They fly great and I get consistent groups. I really don' t think weighting the shafts is necessary. At 20 yards, it will do the job on a deer. Remember, back in the 50' s and 60' s, the average bow was a 45# bow and not as highly designed as those we shoot today. Heck, I' m getting 180 fps from my 50# bow. My first compound wasn' t that fast! Dick
