Athlete lots ("rainbows" of base/parallels/inserts), "team" lots of the key teams like Men's/Women's Swimming, Track & Field, Women's Soccer, Women's Hoops [very chick-friendly set], hits individually, key parallels and base cards individually, and the rest in u-pick lots for set finishers. Gave up selling base sets individually on eBay - not really cost-effective IMO - sold them in bulk to a dealer. Lots of hours invested - hopefully it will pay off!
"I'm told that since the eyes of two people cannot occupy the same point in space at the same time, each observer sees a different rainbow. The same, I think, could be said of the past. The past is what happened, history the way we remember." Gerard DeGroot
