I would choose a Heym, not the Jumbo but a 88B. I believe that the locks of the 88B weaken the stock considerably less than sidelocks do and their trigger pull and safety level is just as good.
I have no experience with Searcy doubles but can tell You that the Heyms are much better than the Craphoffs. Merkel knows how to build doubles but I like the locks of the Heym better.
If You have enough money a custom double could be worth a consideration.
Just MHO.
