Thanks for that, but I bought one of those new models a while ago to discover that it feels not much like the older model. I still have the newer one, and use it for short trips on the tandem (set up for a 3 year old so we don't go far) but it is not the panacea that the old model is.
If anyone wanted to trade in their old model for the current version I would be prepared to part with my newer version.
