If funds are an issue, you can go a long way playing WGT GI2-S balls with the G25 L59 irons. I don't wanna shell out for balls, so these cheapies are doing me fine. I'm TM approaching Legend, and can fund my ball usage from free weekly tournaments.
I do, however, get thoroughly out-driven constantly in head-to-head games, which can be a little emasculating.
