I'm definitely in the mylar camp as well. With the the 2PAC (and a little wax down) you can always take that mylar back up if it gets dirty.
Will it need the mylar in the next 5 years of play? Probably not. But what about 10 years from now? How about 20 or 30 years? Who can predict how many plays it may have on it by then and if it would wear through? If you went to the trouble of 2PAC, I assume you want this to remain a show peace for a long time.
When I restore a game I'm not just doing it so it looks great now, I want it to look great decades from now.
