On my last FZ I went through several sets of Maxxis Sports, did track days, mad races round France (3000 miles in a week), toured 2 up with the wife and found them to be excellent although because they're so soft they don't last very long, price you pay for grip, and they do really grip. Nice feel too, predictable, turn in nicely without that falling off the edge feel you get from some tyres.
Lots of people knock Maxxis but they've never tried them. Current FZ (just bought 2010 reg with 2400 miles on) has Bridgestones, suspect when they're worn out there'll be some more Maxxis going on.
