Using Dunlop Silk at the moment. Seems pretty good, not that I have ever been able to really tell much difference between strings but it feels comfortable and after a fair bit of play I have not noticed any loss of tension or wear to the strings themselves. But when these go I will probably just re-string with something durable that retains its tension for a decent amount of time.
