Although I seldom shoot a recurve (prefer longbows), my favorite string material is Dynaflight '97 (for bows made to accept low stretch materials). I don't care about a few extra fps. I like the durability, lowered hand shock, reduced stretch/creep, and don't have any problems getting it quiet. I've never had a dacron string on my favorite longbow, and after about 10 years of being my "go-to" bow for hunting, tournaments, practice, and play, it shows no wear from the string.
Ask whoever you order from about whether or not to order it short. If you go with dacron, it's going to stretch--a bunch if the string maker doesn't pre-stretch it for you. I don't take orders on AMO bow measurements if I can help it--might or might not be correct, as a lot of bows don't go by AMO (AMO is 3" shorter, longbow or recurve).
