Me and my kid have been oogling tag-alongs for a while, but it just doesn't feel safe mounting one to my thin alu seatpost. So a Piccolo perhaps would be better and it also seems popular on the internets. It does however only fit Burley's own Moose Rack.
Being in love with my Tubus Air rack, I'd hate to have to switch it out for some weight-weenie heresy. Most of the time I use the bike just by myself anyways, mostly for fast paced commuting.
Do you think it would be difficult to mod the attachment device to fit? The Tubus is really narrow, only 66 mm wide @ the top.
More importantly, would you consider it safe to use a rack not designed for it? The Tubus is quite strong, designed to carry 30kg and never wobbly even with my panniers stuffed with groceries; but still?

Wouldn't putting a steel seatpost in be the simplest course of action?
Not only that, I've gotta believe that mounting a tag-along on a "thin" aluminum seatpost very close to the frame of the bike is going to be much more secure than attaching to a rack (particularly a rack not designed for such forces).
If you're concerned, get a steel seatpost. But I think it's likely you'd be making the situation more dangerous, not less (and significantly so).
Thanks to all above, I appreciate your input and have decided you most definitely are smarter than me. I'll get a secondary bike or a tag-along designed to fit the seatpost, even if it means I'll miss out on the praised Burley.
