I've used Summit and actually like it. There are a few hops that if you use too much, you get onion, or cat piss or some nasty flavors. Summit is one. Use it sparingly, don't over due it and I think it can add some wonderful flavors and aromas. As a matter of fact, try using it as an aroma hop at knockout or a flavor hop at 15. Just don't go throwing in half a pound per 5 gallons of it. Think of cooking. Some spices give a lot with a little and have amazing flavors but if you use too much of it, it kills the meal. Not all hops should or can be used in the same amounts as others.
