When comparing a short and very reflexed bow with any "western" recurve, they are
1. shorter -> sharper string angle -> better release needed -> more challenging
2. no arrow shelve -> adoptions in the shooting-technique and/or you need better matched arrows -> more challenging
3. lighter -> more mass would make it more stable -> more challenging
And comparing a longer one, they have
1. heavier limbs -> less cast or more handshock, or both
2. lower braceheight -> again harder to match arrows and torque has more influence.
I shot hunting recurves, a Hoyt gmx with ilf limbs, modern longbows ... and I could mess up my style so badly while still hitting okay, but with my current short Korean bow ... nope, any minor flaw educates me. Comparing it with a selfbow, I wouldn't know where to put my money. To me, they are pretty close. The Korean one is faster, making up for misjudgement in the distance while the selfbow allows me to shoot tighter groups. There is no need to generalize my experience, just want to share it.
