SO i go to Sportsmans to get new arrows and tell the guy behind the counter to set me up with the arrows he would prefer to use on a bow that shoots 28'' arrows at 275 fps with 66lbs of pull and use 100 grain tips. he sets me up with goldtips 3555. Now my question is why later do I see that gold tip recommends 5575 for my setup? the 5575 are 25 grains heavier and im guessing flex less in flight. do you guys think I will be ok using 3555?
