Track 10 was by far my favorite from the Track series. I can't imagine too many people are willing to break up their track sets, but fortunately they did release the remaining bottles to people who bought the sets a little while back. They could buy 2 additional bottles each of tracks 4-12 I believe for $20 a piece. Those unsold were available to the public, but I am fairly certain 10 sold out to the box set owners. With that said, I imagine it will be a bit tougher to trade for. Those who have had it know how good it is and probably aren't too eager to let it go. I'd say something of the limited nature in the $20 range is probably a good place to start, especially something that doesn't show up in San Diego. As far as track 13 goes, I don't believe it was ever available to go from the brewery except for part of the box set. I don't put it quite on the same level as track 10, but it is probably more limited and fewer people with more than 1 bottle. Good luck!
Yeah I think for sure a dbh would. 5, 7 and 10 were the best in the series for me. Throw out an ISO:FT and u shouldn't have a prob if u offer up either of your CCB brews. Cheers.
