I was motivated to post this because of another thread. I didnt want to high jack somones elses.In September I will be going on my first ever elk hunt. I have GT 5575 that finished arrow weight is 399 grains. I shoot a Hoyt Carbon Element at 65lbs. The Goldtips are tipped with a Slick trick standard 100grain broadhead. These arrows have always shot and tuned very well for me. My concern is their overall weight. I added a 20 grain weight in the front to get to this finished arrow weight. The chronograph has these arrows shooting around 275ish. I cant remember exact numbers as I have never been a speed freak. My other option is Easton Axis with a finished weight of 412 grains. These arrows dont seem to fly as well or as consistent as the Goldtip pros. These are chronographed at 269 ish. The finished momentum when calculated had the Eastons coming in a bit higher then the GT.However as I stated the Gt have always seemed to tune better and fly better. I know that the heavier the better arrow for hunting. My question is will the Gold Tips be enough for elk? I read so many diiferent opinions/experiences that it is hard to decide.My faith is certainly with the Gt in reference to tuning and consistency when shooting. However I am not sure given the other weights others are shooting for elk. I just want to give myself the best overall chance should I be lucky enough to take a shot. I am not sure regarding grains per inch or momentum, what constituents a large difference. My calculations have these arrows rather close numerically but in the real world does the 13 grains of weight make a large difference? I am asking because I have only killed whitetail here in PA.Any help would be appreciated.
