I have owned both but , I have been shooting their standard grip for twenty plus years. With that said I ordered PCH with the low wrist grip to try and could not get used to it. So I sold the bow. If you primarily shoot longbows I would stick to the grip that is closest to your longbow. If you want to switch back and forth.
Could I have gotten used to the low wrist? Yes, but to switch back and forth with my regular grips no to much of a pain.
Have fun on the tour, I flew out a few years ago and got the tour. A finer group of folks you will not meet.
