I have since bought and tried out the sure tone. It is very adjustable, and comes with 2 sets of pads that you can use. The inventor has a website on which he talks more about the rest, and shows how it is used (and why it helps with resonance). I would recommend it. I have not tried the other one you mentioned, and I apologize for not seeing your question until, like over a week later. I will remember to check the little box below so your response will go to my email.
