gibson acoustic j 200

I recently bought an acoustic guitar and I do not like the chains do you recommend I get?
I bought an Epiphone EJ-200 and I love the guitar but the chains rattle a lot, even when they should not. I thought the canals of Gibson J-200, but I'm not sure. What do you recommend? so is the difference between nylon and steel strings?
Some time ago, bought silk cords and money. They are wrapped in silk strings, and are easier on the fingers than steel, but not as soft as nylon. I was very happy with them on an acoustic. I do not know how they last. Sounded good.
