I think if you go to golftown you would have better results using shaft labs and the vector machine, i think its $40 and they will tell you what loft and what driver you need to use. You can also go to artisan golf as well. Better to get one of them do it for you then trying it yourself in the SIM because those sims arent as accurate as the vector machine and on the SIM unless you know what all the numbers mean its pointless. Leave it to the experts
