You could try light-mediums (or is it Medium-lights?) where the treble E, B and G are lights (12-54) and the bass E, A and D strings are Mediums (13-56). Makes is a little easier on the hands while maintaining the bass growl you want. That's what I did with my mini...
I tried lights and lost the sound I fell in love with on my mini so I put on a set of Elixir PW (11075) Light mediums ( 12-16-24-35-45-56 ) and been happy ever since.
I feel the light top & medium strings helped me ajust to it a little better.
Will probably try the mediums next (13-17-26-35-45-56 ).
The Mini is one sweet little guitar. Now I want a 414 or 614 if and when the budget allows.
