If you want to try something really different, try flat would strings. Even the light gauge flat wound strings will feel heavy compared to round wound. You'll have a completely different tone. You'll also have an ultra quiet fret hand. It's really a different feel. Caution, I wouldn't put these on any guitar, just the ones that have the neck to body integrity to handle it. My '76 LesPaul has held them well for several years with no problems.
You might love it, you might hate it, but it's definitely different.
