I just swapped the 1100 in my countryman to a 1.5" - runs fine.
Son has done the same to his K. It's the way to go
(unless you have a really worked 1100 - then go for a 1.75")

Ok well thanks all for your opinions.
I decided to go for the webber.
Dropped the old girl in today and i'll pick her up week after next.
New valvestem seals, service, new carb, wheel alighnment, suspension set up, brake service and fix the handbrake.
She is going to be a rocket that turns and stops. As apposed to a slug that handles like poo and hasnt got a handbrake.
YAY for the local mini man
