yeah, unless i sharpen them too much :-), btw these blades are so fast for spinning it so much fun!

Hopefully, you have a good blade sharpener who won't take off too much with each sharpening and won't flatten out your rocker over time. If the Gold Seals are easy for you to spin on even though they have an 8' rocker instead of the 7' rocker you're used to, it's probably because the rocker on your old blades had gotten flattened out a little over time so it was behaving like an 8' or 8-1/2' rocker by the time you switched blades. Anyway, have fun and enjoy your new blades!
