You gotta remember Gaetano doesn't hang around a bunch of Pro Posers... he's been at the track talking to NASA guys... running TT and other classes. They are doers.
Read the NASA forums (these guys run on the track more than post on the internet about wanting to run on a track). Many indeed have been switching to A6 in recent years over the R6.
Wait, did I just give Gaetano a compliment?
Can't we talk about 200 TW tires again?
