My bottom finger (split finger) is beginning to give me trouble. I guess I am getting old. So, I am switching to three under. I feels real awkward and my accuracy is way off. I need insights from those of you who have switched from split finger to three-under. Things like arrow tuning, bow tuning, etc. would be a great help. Both of my bows are not tillered for three-under. Does that make a lot of difference? Mark
