Purchased the XP-1 from RBG recently. Have hit on the range and played 18 holes with it twice so far. I like it!! The 43g Honma shaft is a bit whippy, but it is a very powerful combination, as long as I don't overswing. Launches high, straight with a penetrating ball flight. Think it works quite well for people with slower swing speeds. I made no adjustments and am using the standard (as received) shaft setting. It was on sale at a reasonable price (52% off retail) from RBG.

I purchased the Honma XP-1 Driver and went with a regular shaft instead of a stiff shaft driver due to a shoulder injury. Overall I like the driver but there is something inside the shaft that moves up and down that makes an annoying noise but does not seem to effect the performance.
