I play in a Brass Band that competes in NABBA's Championship division where it seems many of the pieces call for the use of a mute.  I have a F Schmidt/VMI 2103 BBb tuba and have been borrowing a Humes and Berg Stone Lined mute (biggest mute I have ever seen, >31 inches tall).  It does not sound too bad and the intonation is fair.  However I was playing with one of my peer's mute that is much smaller and was surprised when I could not even sound the low BBb (not the pedal tone). 
Without being to technical, can someone explain what the shape of the mute'e effect is on the intonation.
Also, I would like to eventually buy one.  Anyone have any good experiences with a specifc mute in a VMI 2103?
