I also shoot with a high wrist grip and have done so for more than 35 years. At the time, all bows had a large grip and it was the only way I could prevent right/left misses. It was also a carryover from shooting recurves
Only recently have I experimented with shooting a low wrist grip and after a good long try, I'm back to shooting "the old way". I did shoot well with the low wrist but had some unexplained right/lefts and paid more attention to tension in the bow hand with good results. I could probably switch completely to the low wrist but I think it would take a few years to be completely confident in my shooting with that style. Not that it would take that long for someone starting out but it would take some time to un-learn my high wrist habits.
