I went with the Hard Top. I actually called Bethania for their recommendation for my needs. They recommended the sport or the hard top, and strongly suggested against the Ace.
The Sport is probably a better way to go. Although the tubing on the Hard Top meets the requirements for Solo-I, you'll be hard pressed to get the 2" minimum helmet clearance unless you're really short. So the sport will meet your needs just as well with a bit less weight, a bit less cost, and a bit more clearance on the street.
Do not attribute to malice, that which can be more readily explained by stupidity.
