Here is what I got, I bought some easton flatline 400's at 7.4 Grains per inch, I shoot a DXT 27 inch draw at 70 lbs, so to stay in spec, and to be able to shoot in a few compititions in the hunting class I need the arrows to weigh 350 grains. at full lenght andwith vanes, wraps, nock, insert and 75 grain tips I am at 360 grains. but i need to take 5 inches off the arrow so I will be about 27 grains light. I dont dare leave the arrow full as I think I will get to much spine bend as i dont want to increase tip weight for the same reason.I am at about 2.3 inches off center for balance point. So at this point I am looking for some input. or am i over thinking it and just go to 100 grain tip, and be done with it?
