The solid fiberglass bows aren't as old as laminated recurves if you note the history of modern-type bows. The first ones showed up in the early to mid 1950's, when uni-directional fiberglass became available. They are sluggish for the most part...heavy limbs and not much riser, and will require a limber arrow. There is a reason that they never became popular as a hunting bow, and were mosltly relegated to starter and youth bows. They will work, of course, but you have to adapt to them.
