I'd suggest doing a series of single hop IPAs to discover what you like about each. Use the same grain bill, hop schedul and process with each one and just change up the hops to find how they taste and what you like.
^This is a good idea. And don't be afraid to blend them in the glass. It's a nice way to learn different hops, and then see how different combinations play together.
Ah the elusive taste and whiff. I remember when I was a wee lad my father would let me taste the foam on his beer. If I could only replicate that. We lived in NY and it was the late 50s early 60s when there will still numerous local breweries competing. Similar to today
