with a 400 light is the answer, again mohawks not sure what the mohawk in gbc brand hit the scale at.

 

Mohawks are very responsive, especially in the 21" variety. My friends did not like the Mohawks on my 440. They are borderline darty. DuneTrackers provide much better flotation and therefore a MUCH smoother ride than the Mohawks. I have not ridden Sand Star fronts yet but have heard they are much like the Mohawks in weight and performance only in a molded carcass.

I will probably run 22" Dune Trackers up front and 22" Sand Sharks in the back this year. These are meant for all around duning without consideration of what is "fastest or lightest"
