Anyone know where I can obtain one? Is there more than one kind? Ideas on which to get appreciated.

On the Cal-40, we may carry about 500 pounds of backstay pressure in 5 kts. and 1200 pounds in 10 kts. As the backstay is progressively tightened, the mast is bent aft, progressively flattening the main, another good thing.
