Hi Cathie

Don't be too quick to put yourself down - you are probably getting more of an ear for what is right,

I didn't finish earlier - heavier gauge strings general give a better tone but are harder to play particularly if you like bending the odd note. So string gauge is a compromise between tone and playability. I find playing all night with heavy strings and a high action is quite wearing but slightly lighter strings mean I can play much longer without finger fatigue.

With strings it is worth trying different types and gaugesespecially if you're not totally happy with your tone.

Hope this helps a little
