Hi David, Just wanted to let you know that your not alone out there if you decide to tackle the Master Monster Set. I shifted my focus on the set at the beginning of 2011 and away from most other cards, comic books, stamps, and coins. So far, I average 2 cards a week with all being tougher backs. The 3 lists mentioned are great references. I use all 3 and also PSA and SGC population reports. The only advice I can give is just stick with it. Its possibly one of the most difficult set building tasks out there but thats what makes it fun.
