Was my experience with BH as well. Bought a bottle as a gift for someone who enjoys lower proofs, and when he poured me some, it was exactly as you described. Like drinking water while sitting next to someone who is sipping Booker's and occasionally exhales into your face after a sip.Had a few pours at a BBQ yesterday, only "new to me" one was Basil Hayden Toast.
It's as if Miller Brewing Co. said "Let's make Miller Lite Light. And make it extra light". Might as well drink Seagram's.
Came home and had something a bit more substancial.
