I'll be darned. I figured our shop was normal, apparently not! We're not very far from Derby Worx's HQ, that might be why they carry so many. You could always order them from the online scout shop, scoutstuff.org?
If you do that, you'll get good ones and bad ones. Out of 20 sets, I usually score 4, maybe 5 usable sets with the rest needing truing. Some are definitely clinkers, though.
If you want just good sets then just buy them from Derby Dad. I'm sure he could fix you up with any style you need.
