April 10, 200420 yr Author This Driver may look a little familiar some PGA Tour pros put it to the test late last season. Its a TP with screws called the 510 prototype.
April 10, 200420 yr Author The final proto before the R7 is called the GT4 prototype. created June 2003, 1 year after the first proto.
April 10, 200420 yr Yes indeed to see the different stages it went through is interesting . Thanks for the pic's Chris .
April 10, 200420 yr Wow Cool pix. I think Justin Rose was using that R510 Prototype with the screws. Who else was using them?
April 11, 200420 yr Great pics! Thanks for sharing them. I actually like the r510 proto better than the r7 out now, not as "busy" in my opinion.
April 11, 200420 yr Author Awesome pics. Is that the same magazine that has the masters bag pics? No it's not. This magazine is April 15th edition, Golf Today. With Toshi Izawa on the cover. At least 15 different monthly and weekly magazines about golf are released monthly in Japan.
