I had new skinwall ones on my Avanti Ridgerider in '94. My bikes had Tioga rubber up to then. After about 6 weeks or so when the rear was worn out I remember trying to get a replacement and whether it was SC, HC, Hardcore, 2.10, 2.20, folding or wire, all the Smoke and Darts I could get for the next couple of years were blackwall...and I went through quite a few as my weekend bike was my race bike was my commuter was my playbike in those days!
This I might try when I work my way up to a more desirable project than my IBOC... I don't think I could justify shredding a Porc on anything short of a top biscuit bike.
