I'll chime in, in favor of the Burly Nomad w/ the rack extender. I've maxed it out for inter-urban portages (100lbs/45.35kg) and have been quite pleased at it's relative handling under such a situation. On a more regular tip, I use mine to take my dog around town (to the vet etc) and feel more or less just as nimble as I do w/o the trailer attached.
