Glad you liked the set up.
I'm afraid the trick with three wheels is to have two wheeled back up for days when you really need that extra feel of flowing movement. It's expensive, even when the two wheeler is an MZ!
Definately try and get a ride on trike and an outfit before you buy. A wide trike (half a VW type thing) can be almost like a old sports car, open and a little bit over powered for it's tyres, so fun on the right road. A narrow trike, which I've only ridden a few hundred meters, feels like a bike until you get to a corner, then it's like a cross between a kiddies tricycle and a really badly set up outfit. I followed a chap on one through some twisties in Wales and he was doing 20 mph on left hand corners an outfit would take at 40+. They seem to be aimed only at guys who really must have a Harley or Wing, don't want to give up solo bikes, but can't take the weight anymore. An outfit is about using the assmetric power to your advantage, getting load off the chair as you need it, using the weight of the chair against the drag of the bike to get it to turn etc. They are very different vehicles, some people love planning their way through each corner, some people hate that they think it's trying to kill them, hence try before you buy!
Dogs, wives, picnics, children, crates of
, BBQ's that's where three wheels do come into their own.
Enjoy what you get.
