I absolutely love it! DC2 hasn't arrived yet (we've got a good couple of months before that I hope) but I wanted to get used to it before so plan to use as a single for the summer. Desperate to take it out for a proper spin today with DS but 'tis raining and my raincover hasn't arrived yet 
Thanks to Tiggywunkle once again for all of your excellent advice and photos, I think it will do the job just fine with our age gap (newborn and 2.5 yrs) and will give us the longevity that so many other tandems won't.
And, you can have 2 children in it and still use the massive shopping basket...that's got to be a winner 
and do you know what, I think I may have come up with a cunning plan to solve the issue of baby-too-big-for-cocoon-but-too-small-for-front-seat conundrum....Watch this space, I am going to need to borrow my friend's baby to see if it works but I'll post details on here when my experimenting is done
