I have recently got my new 714 ap2 with a R300 xp95 +1" longer 2up (6´35" tall).
I tried before this shaft with a 0.5" longer because they didn´t have +1" longer in the demo material.
I ordered D2 SwingWeight but they have got D4 with a midsize grip and something else that I don´t know (perhaps a lighter head). I have probed them three times in the practice court and I feel the clubs too much heavy related to the +0.5" longer that I tried before.
Kind regards from Spain.
