According to the tracking info it looks like they originated in Boise, ID. (I delivered the unopened package with the unexamined packing slip to the shop that mounted the tires for me yesterday.) My last tire order via Motorcycle Superstore took forever to get here from Kentucky.
I'm going to give the 720's another shot. My riding ability has improved since the last 720's and the rear 712's seem to be wearing quickly. I've also learned a lot about suspension adjustment since the 720's so maybe the original blame was undeserved. I think the 720's are supposed to be more durable. I'll see if the 720's inspire confidence in the corners.
