It all depends on the player. The SP's in the set all have only 3 backs with cycle being very very scarce and comanding a massive premium over a normal cycle backed player. The cycle will always command a small premium over most of the other common backs. It's the tetering point in the backs. After cycle you start seeing bigger jumps on cards. A $15 common in poor condition will fetch $40-50 with an AB back. Not much more than $80-120 for the BL and probably $300-350 for the Drum. If it has an AB green it will not have a BL or Drum back. So AB greens to me are the top card since the AB blacks can have BL and Drum parallels.
