It would obviously be nice to be custom fitted using Pro V1x on a beautifully prepared surface, but that objection to conditions and equipment at least in part misses the point.
A lot of the analysis during custom fitting is based on how well you deliver the club to the ball, and if the machine determines you have a very slow clubhead speed, steep angle of attack and leave the face wide open, then it doesn't really matter if you were aiming at a Brussels sprout sitting on a pice of astroturf or a Pro V1x on a tee at Augusta National - you now know a lot more about what is suitable than you did before.
But if you don't think it is a good idea, don't do it. Wander into AG and have the guy look at you and declare "you look like a regular flex, one degree flat, mate". I bet they will have whatever he thinks is most suitable in stock. Or should that be the other way round?
So are you saying that from impact through the ball onto the turf and type of ball has no effect what so ever on custom fitting readings?
