I'm in a similar boat. I grew hops for a couple of years when I first started brewing, but I ended up growing varietals that I don't really have an interest in brewing with. I decided to restart 2-3 plants this season, but I've been looking for something that I'm actually going to want to use. Cascade and Centennial don't do much for me, since every commercial brewery has used these to death. I'm definitely going to grow Sterling, since I use it in my lagers quite a bit. My others are going to be two of the following:
Sorachi Ace
Crystal
Glacier
Pacific Gem
Kent Golding
I'm leaning towards Sorachi (from Farmhouse Brewing Supply) and Pacific Gem (from Great Lakes Hops), right now. But Kent Golding is tempting to try since I often brew English ales over the winter.
