Roger - I appreciate your prompt responase. I thought your suggestion was excellent. The lettering on the fin was slightly proud, so I smoothed the fin down.
I was fortunate to be able to test the theory yesterday, and was still having spin-out problems, but only up wind this time. I am starting to think that my spin-outs may be technique-related. I was pretty powered up, and may have been using too much foot pressure. A more upright stance seemed to alleviate the problem. I will work on it.
I do think you are on to something with the raised lettering, so make sure that Drake is aware.
Thanks for your help.
