Repto,

The Burley Piccolo I would recommend as the middle vehicle. Most of the seatpost mounted, er, mounts, are not overly robust. Put a 25 pound trailer plus child seat plus precious child, and the safety factor becomes less than good.

Take a look at the Burley web site. The rear rack mount is strong - they call it the bull moose rack.

More later.
