Lots of interesting information to sort through. Although it's tempting to try a heavier gauge, I think it could damage the guitar. However, there are a few new names of strings that I will try, also some names I've heard (like Elixer) but haven't tried yet. I haven't used Martin guitar strings in a while, maybe that's worth looking into.

Thanks.

btw the I just heard someone last night playing with new D addarios on his Martin 35, doing a semi folk- semi-classical version of Classical Gas, and he sounded amazing! So did the guitar. BUT he is an incredible player. Could probably play with the guitar string with rubber bands and sound great.(Guy if you are here, this compliment is for you).
