Hi Kim
What I am going to say is highly controversial, but to me the most important thing right now is that you are willing to pick the guitar up and play.
I have never tried nylon strings on an acoustic so without direct experience I would not put a comment forward. I don't even know how classicals are strung, on your acoustic your strings have little ball ends that the pins lock in place.
However, as I stated on another post, I am a 57 year man who put 9 gauge electric strings on my acoustic last January when I started playing and it was the best thing for me to do. I did not like the 12 gauge strings that were standard on my guitar and I believe are on yours. And as I type this, I am playing our Yamaha APX500 which I threw a set of 9 gauge electrics on the other day as I was responding to a question by another member. And again, this is not proper. But to me there is no wrong way if you are going to instrument and practicing. And whatever you need to do to make that happen should be done.
This year the diet is definitely gonna stick!
