Hello everyone, I'm currently using 910 4H and 5H. I'm kind of interested in the 6H they recently introduced, but I only find with regular or senior flex shaft on online stores. Any idea whether it will be available with S flex? If not, I might just get a shaft and pull out the stock shaft - Bassara W 50. In this case, which shaft would you guys recommend? I'm satisfied with the stock shaft for my 4H and 5H - Diamana Blue - but might as well try a different shaft too. Also, does anyone know the swing weight of this new 6H?
