Welcome EG,

You've had a good start. Similar to mine. My first four bourbons are from your list, except replace ETL with Buffalo Trace.

What has helped me, with advise from the members here, is to isolate the taste of wheat or Rye in a bourbon. Doing side by side tastes of Wheat vs. High Rye is best. Of the bourbons recommended to you so far:

Wheat - MM, Wellers
Rye - Wild Turkey 101, Old Grand Dad 114 (you might even try a straight rye, not bourbon, for this exercise...WT Rye, Rittenhouse rye.

good luck. looking forward to your future posts.
