Until you settle on the perfect brand and gauge, always keep the empty pack of whatever strings your currently using in your case/gigbag so you don't forget what your using. I can't tell you how many times people come in the shop and say "I love the strings on my guitar but I forget what I used. Can you tell me what these are?" Unfortunately most strings look the same so it's very hard to accurately answer this question so the best we can do is measure the thickness and get you something that's the same gauge.
As always, consult your friendly guitar store employee to get a good recommendation and to answer any string questions you might have.
