Where did you find Four Roses lacking?
Just not as smooth and easy to drink to me as the Eagle Rare. I had a few fingers of Four Roses and then a few fingers of Eagle Rare. The Eagle Rare was better to me.
But I guess my bottle of Four Roses could taste different than your bottle of Four Roses - single barrel and all.
I'm 50 Y.O., but have only been drinking whiskey for about 2 years. I'm still learning a lot.
