The Heritage Chrome sets are some of my favorite WWE sets, but more because they are Chrome, not Heritage.
I would love to see another Chrome set, regardless if its heritage-style or uses a modern look. I'd like it to include a full compliment of color parallels just like any other Topps Chrome product.
Oh, and you know, actually number your parallels... which Topps has neglected to do in the last few years.
Museum Collection would be my second choice... if it included on-card autographs.
