Have a couple of these in my trailer fs...
If I stuck to my regular schedule (which I usually do) they'll have one Sunday practice, followed by three races, two, maybe three track days on em at various paces, then one more Saturday practice at the next round where I'll rip out a few 17's with no issues and swap it out for a fresh sneaker for the races. So they're definitely still decent for just about any track day enthusiast on a lightweight bike.
Payment: $50 for one, $90 for both... obo
Delivery: You can come pick up in Quincy or Danvers (or meet somewhere local to either of those locations). Or I can deliver to Thompson at the next TTD or Loudon for round 7.
