What i look for in a product is value...
1. Higher end inserts must be numbered. I know a few people will say they are neither here nor there on numbering but Select's recent Dynasty release...and even the Lockyer auctions for specific numbers they did on their website, proves that there is a market for specific numbers...which ads value to the product. (Yes, i have heard that ESP have said they will be numbering in future)
2. Ratios and Production level. There has to be a good blend of inserts at varying ratios. If there is a "case hit" card then there also has to be other high end cards in the case to decrease the chance of sellers "case searching". Terry has said they want to try and crack down on searchers, however, the first ESP release did not do that at all. I think Select's Dynasty series this year did a good job of this. In one case you would get a card #/100, 2 cards #/50, 6 cards #/150....as well as numerous other inserts. On the flip side, the year before when Select did its Strike series, I for one did not purchase any of it because IMO the inserts and ratios were poor.
