I have been struggling to find the right strings for my 2011 814ce. Tried all the usual ones plus Straight Up Strings. Some sounded ok...some bad but none were giving me a warm rich sound I was looking for. I bought a set of Dunlop PB 12/54 and almost didn't even give them a try but once I put them on I was amazed. Its been two weeks and they still sound great! And they do not cost much! I found it curious that I have not run across anyone talking about theses string!!!!
