I use "lightweights for wheels" on my Troll, seen here: http://i1035.photobucket.com/albums/...5DEA8782B8.jpg Very bright and it expands tire choices as it applies to the spokes.

I disagree with Sheldon's rotation theory. I rotate tires. You tend to pay more attention to the front tire, so you'll notice wear and tire issues quicker. Especially important when running fenders and the rear tire tread is hidden.
