Not meaning to state the obvious but have you tried searching the ISO:FT forum to see what it might be going for? http://www.beeradvocate.com/communi...l+Waters+16&o=date&c[title_only]=1&c[node]=25
Also not helpful but I got two from great traders for anything I felt good enough. One bottle is going to a great regular trader who was searching for one. Make good trading partners and these bottles become easier to trade for.
I traded a guy up in wisconsin 3:3 with hunaphu. I think you could Get that or anything similar with rarity and deliciousness.
I've traded a number away. One trade expanded but the initial core was a b5 & b6 Beat for 2 bottles of 16. I've given them up for less and extra'd one away but I wouldn't consider those to be typical trades.
I have traded CW16 for the following (sometimes with adds in one direction or the other to help even $4$): Gratitude Chocolate Rain MoAS Life is Like BA Big Sound BASS I've also traded a few bottles as part of larger trades, but it's harder to equate in those cases.
