Sorry Flip, nothing in the Mistral range that appeals.
Thanks Vince, I've used the Classic Bike Shop a few times for Commando bits, they are good quality and priced okay, quick delivery too.
Replica Contis seems to be the way to go, adaption shouldn't be an issue as they will probably be on bespoke pipes and mountings.
DP Contis would be an easy hit on Monster pipes to start with in the unlikely event of a nice pair materialising, but I'm not holding my breath.
This has been an interesting exercise though, thank you to all for your input...
