Thanks for the responses all very useful, I should probably have said that I'm in the UK. I've been in touch with the UK distributors for Precision Rifle today and they've both confirmed that the Rifles have been discontinued :-( Which leaves me with a bit of a dilema.
I was fitted for these clubs and seem to recall that the Rifles were recommended because they were light and offered a high launch angle which suited my slower swing speed. Required specs for the R7 TP would be .355 tapered.
I'm therefore reluctant to go for the S300's as the high weight and low launch goes against what I need. I'm therefore thinking the Dynamic Gold SL S300's, KBS Tour R+ or Project X 5.0. All seem to have similar weights and flex (the S300s would be slightly stiffer I believe).
Any thoughts on the above? Any other factors I should be considering?
