Hey The Scythian, nice post.
I would advise the OP to go with a modern recurve based on the information he has given us. Just for ease of use. I have a Korean Horn Bow both a composite and the actual horn bow. They are a lot of work and or very difficult to shoot without training in the traditional manor. Particularly if you are utilizing the thumb ring. The training I received helped but even then it is more difficult to work with. Where as a modern recurve is a lot easier to use and also to get some basic instruction to begin.
