It is a minor expense...but that wasn't my point (which I didn't make
very clear). It's not the actual cost I was referring to, but the
amorphous principle of not wanting to pay more for something that
doesn't deliver a benefit worth the extra money.

OK, *now* you're talking. I'll need clear insulation though (to show
it off) and none of the hi-temp stuff is clear....darn.

A few bots out there stall under "normal" driving conditions, but very
few. Most easily spin their wheels when placed up against the wall.
It's almost a requirement since most bots might have to carry the
weight of another and you need to have that extra torque in reserve.
Until that other bots is on top, we enjoy the faster acceleration.
