It never really bothered me when they changed because I have a Fox and New Edge also, but I do think it is better off with a classic only format.
I mean, come on! You already have two major late model mags that are each twice as thick as MM&F (M&F again?), why would you need late model coverage in this one too?
I'm looking forward to it being a classic only mag because my 68 was my first Mustang and the only one of my 3 that I will NEVER get rid of. It's my baby.
