I used to play with a wound G string on my electric. I already played very heavy strings and tried it a few times. In the end the heaviest unwound string that I could buy satisfied me tonally. The only reason I played big fat strings was for the tone.
I also pinned my whammy bar by hammering a piece of wood into the bottom of the bending mechanism, whammies steal tone, and if you don't use em often or at all it's worth pinning em down. A nice chunk of wood will transfer tone to the body of the guitar when it's holding the bridge whammy mechanism down.
