Thanks guys, I've mostly have used rotosound swing 66, but have recently changed to Ernie Ball Cobalt Slinkys. The Lakland has these at 50-105, nice strings but really messed up my string height / action. I've already bought the 55-110 & a Hipshot drop D to go on the Stingray and following the comments above like the idea mixing up the sets, but think I will try the heavy gauge on the Lakie as well with a good set up, as this is my main bass.
But many thanks for clarifying the 110 route
