My bad. You will indeed have less caster. Less caster can mean harder to drive in a straight line.
Peakster! how is straight line driving with the doughnuts on front?
It was a bit interesting . There did seem to be a bit more side movement at highway speeds, but I just thought it was because of the wind, and less grip on the ground.
Wikipedia: "A caster (or castor) is a type of wheel mounted with an offset steering pivot such that the wheel will automatically swivel to align itself to the direction from which it is pushed. They are commonly found on shopping carts and rolling chairs."
