The WSM is an impressive little cartridge. Mine is a 1-11 and I find the 190vld was my best performer, my hunting partner use a 230 in his 1-10 and is doing some impressive work with it, even making wish I was running 1-10".
If your convinced you want to use light weights the 1-11 or 1-12 makes sense but.... don't sell it "short" it can do very well with heavies and if you have any doubt at all error on the fast side.
