so here is the overall truth. I absolutely hate going down roads like this. I hate when people suggest things like hey let us try this arrow setup and so on. Everyone has their own opinions about how things work and rightfully so. So no I don't now if I want a 400 or a 350 spine or whatever. I know that I have 2 dozen 400 spine arrows. Now on the safe side I am only rigging up like 3 total arrows to test to see what happens. if I don't get good results then I may either back down to a 125 grain or get a few 350 spine arrows and see what happens. it is all about trial and error and in the end the real kicker is can I, the hunter, put the shot where it needs to be when the time comes and have I practiced enough. All I know to do is field test and see what happens. I am in no hurry because I have a vertix to hunt whitetail with. Even though funds are not a problem I don't want to spend money foolishly. I take everyones advice here with consideration and research it for sure. so keep the advice coming and ill just go from there and wish for the best. I am an engineer by trade and I stay away from experiments such as this because I know what will happen. I will way over analyze something to where it makes me sick and in the end ill realize that I really didn't need to do all of that. So we will see. Thanks for the tips
