I don't have a whole lot of experience with curves as I prefer straight longbows, but I've shot a few, some for awhile and some only briefly. I have found that there is tremendous difference in the grips/risers of curves, both in size and shape. I know that with my smallish hands, this makes a tremendous difference in how well they shoot for me, or perhaps I should say how well I can shoot them. They also usually have a lot more weight than my longbows. The weight/balance issue affects the high/low of my shooting. The overall size or width of the riser can affect my grip and thus the right/left.
I see a lot of threads about "what bow is best" and, to me, it seems the truth is that it is more a matter of how a bow fits or feels to you than who made it or or its style or type. I've sold fine bows that just weren't for me. I think the trick is to find a few bows you like that work well for you and hang onto them.
Even though right now I'm shooting all longbows I've made, I have three recurves, a TradTech Titan, an A riser Bear and a vintage Super Kodiak, that I've held onto. They fit my hand, draw smooth and shoot well. I know if I ever decide to go recurve again, they're there.
