I started tandem riding with my son on a poor-man's tandem (Adams Trail-a-Bike) then graduated to a true tandem (Raleigh Coupe) with much delight last year! But now my youngest son is ready to ride with us and my wallet is not padded enough for a triplet. I know folks ride trail-a-bikes behind tandems, but wondered how well it works as far as stability, handling, tight turns, stopping and starting, safety, etc. Can some of you experienced with a "poor-man's triplet" relate your experience in riding?

Thanks!
