My guys are all AMHR......I don't show any longer, so the question is moot, to me, but what I like with AMHR is that you can have an under mini and attend AMHR shows or you can have an over mini and attend their shows.
For many people that own minis of both divisions you don't have to decide which show to go to, they can all attend the same shows.....overall the expenses for AMHR are more friendly.
