I just picked up a couple of these - a 19 and a 22 degree - and i wish i had done it years ago! I have been hitting them wherever possible over 4-5 rounds and they perform so much better than i anticipated. Solid and long of the tee, high trajectory without ballooning, and strong from fairway/first cut.

Anyone else gaming these? I imagine they weren't totally popular as they seem to have disappeared from the line up. I also have tried 712U and while i liked it, i didn't love it.
