Ditto some of the info above. I've often just sacrificed frame 10 because of the contacting problem. About a year ago, I did find, on E-Bay, a 250-sheet box of Kodabrome II RC (grade 2) in 8 1/2 x 11. With a little finagling, you can usually squeeze most of the 10th frame onto that size paper. It worked well for me because Kodabrome II RC has always been my standard paper for contacts anyway.
