Many of us have also not liked the resonance of the water trough. A few of us have done some to alleviate it but I think none have eliminated it. Take a look at this thread, it has a couple solutions.
I can offer a solution. I use a big roll of tape and put it against the side. Not flat, but with the round side. I use the tape to secure the blade against the clambs, so it is no extra.
