Thats the primary reason I'm waiting to find out how they feel, run on the street before I buy a new set of Bill Boards. My biggest concern with the hand grooved slicks is wet traction. I am in Oregon after all, rumor has it, it does rain here on occasion.
The Bill Boards have really good wet traction, I suspect the slicks offer little in that regard, a valid potential concern. I DO drive in the rain or get caught in the rain from time to time. In fact, I went for a drive yesterday with it "threatening rain" and sure enough, the roads were wet in some places.
I have the tires and wheels right now but have run into a bit of a problem finding the right valve stems I like, so I'm off today to hunt them down. Couldn't find them yesterday after searching multiple sources locally, I may have to order them from some place.
