Thanks all!  Tough set!  I was up 7-5 and ran to an easy 8 ball to go up 8-5.  I just choked plain and simple.  Next thing you know it was 7-7.  He came up dry and I got through a moderately tough rack, then at 8-7 I broke and got a total cosmo and I got the job done.  I was a little fortunate he wasn't breaking too well and I got just enough chances, but I did play well at the end again to get it done.
Yes, Ralf is my hero.  I've played him twice.  He roasted me at DCC once in the 9 ball, and I scalped him in a bank set there a few years ago.  Obviously he is a going to give me all I want.  He's no spring chicken but his style doesn't age out poorly and he's still playing great.  Still, I look forward to the set and hope I can make it a fun challenge!
