Quoted from JayLar:
I've got five sets of brand new Ninjas and two sets of carbon. Think I'm gonna start with the Ninjas until the game is broken in and eventually switch to carbon.
Quoted from crwjumper:
IMHO the Mylar has a purpose and should be left on. Yes you will have to replace it from time to time, but it still serves a purpose. JJP could have saved money and left it off but they think that it is necessary. I buy new shoes from time to time. I could walk around barefoot, but I find the shoes necessary.
I think they are recommending using an xacto to remove the mylar directly on top of the magnet. This would have cost more for JJP to do. The problem with the mylar on top of the magnet is that it gets a lot more force and will cause the mylar to buckle and peel. the magnet should not need protection, I wouldn't think.
