Mark Crossfield positive on the Srixon as well. Might have to wait until next season, as the prices really are eye watering now for drivers in their first year, but I think the Ping and the Srixon will be the two to try.This video popped up on my notifications last night - don't see many people playing Srixons but James here seems impressed with them.
I dont really go for testing one on the course as its just a few shots and a bit random as you can be influenced by where they end up rather than how they really launch. Nor fitters, as they look at cold numbers rather than your swing. Thats why I prefer a pro plus his launch monitor, as he can judge your swing as well and match that to the best club.
