T210 series 6 scarcity question

Okay, a couple of my fellow T210 series 6 collectors could probably answer this for me. I just started collecting the set and I currently have 5 cards from it. I watched the set for a few years though just to get a feel for how often they came up and their price etc to make sure I could collect them and I have to say, while they are all rare I have definitely seen more Womble Shelbyville examples come up than any other T210 series 6 card. That being said I just recently was able to acquire one thanks to the kindness of a fellow board member who had a duplicate, but it made me wonder what everyone thought were the most common cards in the set, and which were the hardest to find not including the stengel in the discussion of course. Thanks
