I liked the lower profile and shape. I just couldn't get them to pattern as well for me as the 4" duravanes. However, it did turn out I still had a little tuning to do on the bow and have not tried them since then.
I did have some issues with them sticking to the shafts, but then I started leaving them overnight for the glue to fully cure and seemed to eliminate that problem. Superglue did not seem to work well but it doesn't work well on my 4 inchers either.
I can drop a dozen to you in the mail and you can try them. I might try a few again just to see now that I am tuned better.
