Overall finish was very good, except for the blade tip profiling. It is also evident that two halves are glued together, and there is no fiber reinforcement across the joint (eg. no tip or edge armor). This makes for a fine edge, but it is also fragile (one tip has cracked from a glancing strike on a submerged stump).
The Lendal joint is a bit finicky, probably due to the nature of carbon-carbon friction. I find it best to pre-wet the joint before tightening the screw only moderately to eliminate rotation. It is not up to the job of making a completely rigid paddle.
What other reviewers have said about rolling and bracing performance is spot-on. It has a very firm catch for a greenland paddle, and is also very buoyant for the static brace. I would give it a ten except for the quality issues, which are not easily excused at that price.
They are great for rolling practice, or rough water paddling such as surf or white-water. They are also good as an emergency backup if you loose your glasses. I usually have a set in my PFD pocket or have the strap around my neck if I'm not already wearing them.
