I bought $20 each of hobby and retail Timelines packs: 5 packs of hobby and one blaster of retail (10 packs). Instead of listing out each card I'm going to break down what I got by subset. This way we can compare what you get for your money in each.
Base Cards: Hobby 8, Retail 32
Base Rookies: Hobby 5, Retail 5
1992 Upper Deck Minors Subset: Hobby 5, Retail 5
1994 All-Time Heroes Subset: Hobby 5, Retail 5
1995 SP Minors Die Cut Subset: Hobby 5, Retail 3
2004 Timeless Teams Subset: Hobby 5, Retail 5
1993 SP Short Print: Hobby 2, Retail 1
1994 SP Short Print: Hobby 1, Retail 0
1995 SP Short Print: Hobby 1, Retail 0
Yankee Stadium Legacy: Hobby 1, Retail 1
Gold Parallel: Hobby 1, Retail 0
Holo Parallel #/25: Hobby 1, Retail 0
Relic: Hobby 0, Retail 1
TOTAL CARDS: Hobby 40, Retail 57
So, what can we learn from this? Well, if you like the base cards then you'll love retail. You get almost 2/3rds of the 50 card set in one blaster. However, most of the cards in the set are the short printed subsets. Since most comments I've seen about the base design agree it is pretty boring, the more subsets the better. There were more subset cards in the Hobby packs by a 30-25 count. There were also more of the short printed SP designs, 3 to 1. No autograph in my packs, but the odds are much better in hobby. The blasters do have a one-per-box relic, but mine was AJ Burnett. Unless he signs with the Braves, It's not that great a pull as far as I'm concerned. In my opinion, hobby packs are the way to go in this product. You'll get more of the subsets (which is the appeal to this set) and there's a better shot at a decent insert. This isn't everybody's cup of tea I know, but it's really the only product that interests me at all right now. I don't know if that says something about me or the state of the Hobby.
