Con't ... I ride briskly but the street is not a track. It would be very interesting to hear from someone who gets his rear end breaking loose to compare the grip of the Powers and Roads and to compare the grip when cold. A lot of street riding can't even warm up a tire.
I know Chris K likes the 180 but I think he is one of those 100+ hp and 100+ mph guys.
I got my three spoke 4.5 on ebay and then got a Crozzeria (sp?) 4.5 on a special run they did. But the 8lbs difference is on both stock 4.5/170 & 5.5/180 OEM three spoke Duc SS rims.
Besides dude -- you practically live on Pilot Rd! The Good Lord Himself is tellin ya what to get! (hehe)
