Kevin- wish i knew you about 5 years ago...i had most of the above mentioned backs in PSA 7 or 8, as well as some strong mid-grades on the tuffer ones (Lenox, Uzit, Drum, etc). i sold them all, and have since rebuilt a respectable back set...but not high-grade this time around. i am sure those cards i used to have are put away in various vaults by now, not to see the light of day for awhile
good luck in your search!
