Take the advice of JeramyK and have them use the premarked arrow and then go from there. Make sure that you let the shop guys know what type of release you want to use or if you will use one at all. That will make a difference. Oh and off the record, I am shooting the VTec. It is the best bow I have used and the more you shoot it the better it gets. Good luck and remember to go with what you like best(shoot everything they will let you)
