Ernie, I don't know about other mfg's of ratchet harnesses - never looked into it. But Hookers are pretty standard in acro planes, and they are pretty much a requirement once you starting doing any negative stuff. Very good quality, and I'd highly recommend getting a set. The 5-point Hooker harness comes with two lap belts - a main ratchet belt, and a non-ratchet backup belt. It's best to have two different areas of the airplane structure to mount the two belts to in order to take full advantage of the redundancy. You can get a Hooker with either two ratchets (one on each side) or one. I think one would work fine for you.
