I shoot a recurve riser bettern than a longbow riser. One exception was oddly a RACO by John McCullough but over time, arthritis created such havoc in my spine and shoulders, I had to drop weight and let the RACO go.
Love how a longbow looks and shoots quiet, but I shoot a recurve so much better!
Recently tried some of the lighter riser mass smaller recurves... couldn't hit consistently with any of them! NOr the smaller riser longbows.
Don't know if it's the grip, but I strongly suspect its got to do with some body mechanics and that, for me, I need the heavier riser mass to shoot consistently.
I'd say go to some good shoots and shoot a lot of different bows from vendors and friends and find what handle suits you best and then order one.
