RE: arrow for setup
How good is good when you say your arrows are flying good? If there are no visible flight problems, your groups are good, and your accuracy is good, do not mess with your setup.
However, considering that the Hoyt Razortec is a short ATA bow, you need to add a few pounds when considering what the actual draw-weight is set at. Factoring in the additional poundage is going to require a stiffer shaft and make 2315 and 2413's your best range of choices.
Did the pro say why he or she thought that 2314 would be a better choice?
