Heh. Fellow GP'er.
'97 GTP here.
Anyway, I've run the following in that size, in order of preference:
Goodyear Eagle F1 GS
BFGoodrich KDW
BFGoodrich KDWS
Goodyear Eagle GS-C
The GS's and KDW's are pretty similar in performance IMO. Both are really good in dry and wet weather but only OK in snow (duh, since they aren't rated for snow IIRC). The KDWS's were decent in all weather but not as nice as I would have hoped in dry weather. The GS-C's suck ass. I only ran them because SLP was selling take-offs and they were cheap. I don't even think Goodyear makes them anymore.
