Yeah, I have a NS solo yoke. It works well for my NW Solo, but I’m careful. I dipped the aluminum clamps to cushion the CF gunnels. It’s short for the canoe I want to build one for, which has a 30” beam. I do however, like the thin wood NS uses. The NS yoke is only about 5/8” thick.
I saw those Swift clamps, but availability is often an issue with their accessories, in addition to the price and the shipping charges to the U.S.
