This beer did have a lot of trub, maybe the next time I will bag all the pellets?
This is what I think is your main issue. Try whirlpooling (you can find the basic procedure on BYO.com or by Google'ing) and use a few different size strainers when pouring into your bucket.
When I load the kettle with hops, I use a spaghetti strainer on top of a finer mesh strainer from the homebrew shop (fits over the bucket) on top of a large fine mesh bag. I usually have to clean and re-sanitize the bag a few times while pouring into the fermenter, but you get a lot less (basically no) hop gunk in the bucket that way. All that trub gives my beer a dirty, "earthy", unpleasant taste.
