I switched to the Supercorsa on my 899 when I changed my wheels to the Rotobox. I used to buy them a couple sets at a time for my Panigale and RR every time Rider's Discount ran a special, but would order them from rockymountainatvmc.com if I needed a quick replacement.
Rider's Discount is shutting their doors and Rocky Mountain is closing out the Corsa Rosso as you indicated and are out of stock.
Personally, I get slightly more miles from my rear than you, but I have further to ride before letting loose on the throttle!
Take care and I hope you are able to take advantage of these unseasonably and relatively warmer afternoons.
