The box states that every pack has a hit in it. Well... in my definition of hit, each card should have either an autograph or memorabilia piece on it. And that's just not the case here. One of my packs had a rookie insert of Kailer Yamamoto serial numbered to 299. The only thing 'special' about this card is the serial numbering. To me, this is not a hit. Things I also don't consider hits are manufactured patches, acetate cards, gold cards, and the like. I'd rather Upper Deck say that each pack had an insert - that would make more sense.
In terms of design, the SPx cards look good and come on a very thick card stock. SPx isn't as wild and crazy as it once was - the design is refined and sleek with none of the 'over-the-top-ness' of some older SPx cards. The cards look great, but I do miss those zany SPx designs from years past. It really made the brand fun. It is, of course, just a matter of taste.
It's kind of funny that SPx comes in packs as there is only one card in each pack. I guess Upper Deck has to vary it up as many of the card products now are of the one-pack-per-box variety. I for one would have been just as happy with one thick pack. Just open the thing and be done with it! I'm sure there will be some people who buy SPx buy the pack, but I truly believe those are few and far between.
With only 4 cards per box, you really don't get a great sample of what the product's all about. Having UD Black cards included further dilutes the SPx cards when busting boxes. I don't mind the Black cards in there as Black cards look awesome, but really... where's all the SPx??? I guess it didn't help that one of my cards was a redemption. I'll have to wait and see what that card ends up looking like when Upper Deck sends it to me!
Judging from my SPx break, I'd say that SPx really isn't worth the steep price for a box with just four cards in it. Looking at what I got, I pulled 2 jersey cars, a serial numbered card, and an autograph with relatively high numbering. I'm pretty sure my pulls were status quo for the product.
Like many of the products that have come out so far, I can't say with certainty that this is a must buy. These middle of the pack products that Upper Deck is releasing right now needs a bit more inspiration to stand out and earn collector's money. SP Game-Used or SPx? I'd personally go with SPx as the cards have a more premium feel to them. None of those silly banner cards too!
