Looks like are really on your way to discovering what tobaccos you like.
Happy smoking and let us know what you are liking/discovering. You will find over time that you will start to gravitate to certain posters due to your similarity in tastes.
I also agree with snewton to try some samplers. If you haven't already, start a log book or pipe diary that tells you x tobaccos you smoke with y pipes, and record your experience. (I know I know, I am a geek). I think this is helping me find which one of my pipes "works" better with certain tobaccos. With that in mind, I would allocate one or two of your cobs to aromatics and keep it at that.
Just my .02
