hello thank you for your answer, it's nice to share, it's a shame (commercial agreement) if wgt wanted it, they could, I think, friends who made me know this game and try their equipment and that we have nothing to do, despite current technology, I bought the sim driver, I have the ping g 410 not much difference, I saw your r11s driver I do not think you would exchange for a driver current :-) it's a shame I think a lot of people are looking for good equipment and apart from a few clubs, we are not spoiled if they put up for sale one or two drivers like yours or the taylomade R1, or a good big wood of big bertha, they would sell a lot, I'm sure, no choice, we will do with what we have no choice ;-) thanks for you answer
