I've never had anything that was even close to JPS17/18 as it's some really unique and good stuff. It's not as oaky or sooty like the W12 can be, and it's not as syrupy sweet and hot like OWA can be. That's why I suggested Larceny since it's more balanced than those two and maybe a little more complex than WSR (even though I suggested that too.) As for the Jefferson's Reserve, that's a hard one to pin down as well. It is not in your face at all nor does it have any qualities that really stand out. It's strength is it's balance and well integrated classic bourbon flavors that drink very easily.
...but I guess none of this matters now since WK has decided to get some PHC 2012 Blend of Mashbills which is just as worthwhile (if not more so.)
