My wife and I are going to replace our helmets this year. We have decided that we're going with Nolan N43E Trilogy helmets but I can't make up my mind as to which headsets to use, Nolan or J&K. I'm sure both are very good and should last a long time, however, I have never used Nolan or J&M products. Any information I can get will be greatly appreciated. While I don't want to start a, "what's the best oil", thread I can use some experience related good, bad, and ugly inputs. Thanks.
