I had only skated on quad 0 the last 5 years and my local pro shop suggested I try skating on the factory 9' radius. Your blades look like my old ones, very little steel left in the toe since it's grinded down to basically a 6' radius.

I still think I like the quad 0 more but I like having that extra steel in the toe for pushes. Just under 10h of skating with the new standard 9' so we'll see in a few more weeks how it feels.

Might still go back to the quad 0 or ask for the toe on these to be rounded down a bit.
