I will try this and report back.
The Dudley two tube system sounds like the best solution, I have tried
e-mailing and phoning them but never seam to be able to get hold of the
right person (Mr. Dudley), to be fair he has returned my calls but I
have been unavailable.
Thanks for the input.

OR - how's this for a stupid idea-
just set the decceleration so slow that the controller doesn't have
stop on changing from suck to blow.
I'd be interested to know whether this is really as stupid as it
