Tasting results:
#1 Four Roses (smoothest/fragrant)
#2 EW Single Barrel (most even front to back-standard)
#3 Woodford (superior scent-aroma hangs pleasantly)
# 4 Killers Blend (coolest, but has quite a bite @ 115 proof)
#5 Shackleton (very Smokey, by far the most inspirational brand) - very slight tequila scent hangs on the end.

Cheers!
