Unless something has changed, we're trying to simplify the sticker sets on here (especially those with players on the backs that normally got tossed after the sticker was removed).
I forget which year we already did, but the idea is to have the stickers as the base set and the backs as an insert set.
If you wish to track your variations, you can do a detailed add for either one, and put in the description which back (or sticker) is on the one(s) you own.
