MikeHey Jim,
How about you just grow a pair ... and yank the stupid thing off, already?! 
Actually Jim, and you may already know this ... besides the perfs, the biggest reason a lot of them don't grade ultra high is because of the amount of yellow (gold?) that shows up on the border of the Tiger card after you rip them apart. Look closely around the sides of the card to see if any of the other cards colors would end up on your Tiger card after it's seperated. I'm pretty sure they max the grades out around SGC/PSA 8 if that happens. I have an SGC 86 that is pretty sharp, but it has a faint yellow line on the right hand side.
Also, I recently seperated a few sheets of the 1964 Wheaties football stamps. I used a thin metal drafting ruler as a guide. I folded them up once, down once, and then pulled up against the rulers sharp edge to tear them apart. I got about 60% PSA 8's, 20% 9's and two PSA 10's. I also got a few 6's, but that was because of bends in the thin stock. (two of which I'm 100% sure weren't there when I submitted them!) ;-(
Anyway, I hope that info can help you out a little. Good luck with the rrrrip!
Mike
