Point taken. I guess I wasn't very explanatory. My point was to keep the
caster on the plus side of zero, anything that you do to reduce positive
caster works against good driveability. Thanks for keepin me on my toes.

Re: Wobble
Since someone is keeping you on your toes, your use of the words "plus"
and "positive" contradict themselves. "keep the caster on the plus side
of zero, anything that you do to reduce positive caster.."
Does positive caster rake the spindles forward at the bottom like a
bike's forks, or is that negative caster?
