Well while at the Bintel shop today to pick up my mount after repairs I had a chance to look at options for the two scopes and wound up with the Losmandy unit but it's the dual fitting one that will take either Size dovetails.
So very happy with that at this stage and it is certainly a rigid plate so I don't think I'll have any problems with flexing and it is so adjustable it will handle future updates without any problems I would think.
Looks like I might get some clear sky tomorrow night with luck to try it out.
Thanks for the input guys.
