No issues with the palm swell grip being thick? The browning I tried a month ago was a little large for my large hands, maybe I am being a bit picky....
When I was into traditional archery, I discussed recurve grip size and shape with a respected bowyer. He said that many people assumed that big hands need a big grip, and that small hands need a small grip. Of course, you don't actually "grip" the handle, but he said that people with larger hands did better with smaller handles. So, counter intuitive?
Anyway, I had gen2 Element and didn't care for the grip at first and actually for quite awhile. Eventually, it grew on me to the point that I didn't care.
I'd just keep an open mind like anything else. Maybe it'll grow on you, if you are able to handle some PH3 prior to buying.
And if you end up buying one, and still can't live with it, then explore reshaping it to suit. Assuming there's enough material, and it's solid. I think they are still injection molded, IIRC.
