I saw the mention of unsprung weight, but I don't think 10 lbs is going to affect much...I've heard that "unsprung" weight shuold be multipplied by 4, etc, but I've never noticed a difference in ride quality from running Aluminum skinnies to the track for racing or wide steel/mags for racing on I-beam axles...besides, I'm betting his tube axles weighs a lot less than the I-beam he had...even with a rack on it? If not, it's neglibale IMO.

I also think he's fine with a greasable slip joint, as long and it's not "sealed tight", so air and grease have a place to escae under pressure...heck, my Peterbuilt has a similar thing (although it's spline with seals on the end) and my slip joint moves an easy 1.5 inches in daily use.

Just my thoughts.
