I finally found some strings to fit my Mod Q5 with a 2 Tek bridge. Ken Smiths with a tapered B. These are steel strings over the nickel I had on before. While the nickel were much easier on the fingers, the snap and presence of these strings by far exceeds the normal lift you get from new strings. I am real happy to find something I can stick with. I did have to buy a B plus a four string set.
