A lot of this is determined by what you want to do with a long bow and how far toward the primative you want to go. If a modern glass lamanated bow is what you want there are lots of good ones, but you should shoot some before picking one. Most will shoot a little different, have different handle styles and sizes, and differing amounts of hand shock, and the only way to know what you like is to try them. You mentioned a rendeuvous and that should mean more primative wooden selfbows. This is more my area as I have built and sold selfbows and cedar arrows at rendezvous for several years now. The same things hold true here, try some if you can, talk to the guys making them, and decided what you want to do with it. These self bows can be made in several styles, lengths, and diffrent woods and materials, so look and ask questions. If the bowyer can't answer the questions then walk away. What ever you pick it will require a commitment on your part to both practice and if a compound shooter completely changing your shooting style. One thing is for sure you will have a lot of FUN doing this,
