Tongue-blocked overblows & overdraws

[JOHN THADEN <JJTHADEN@xxxxxxxxxxxxx>]

Hi,
  I'm curious whether anybody out there can get overblows and overdraws
reliably, quickly, and musically while tongue-blocking, either side-hole
or center-hole.  I love to tongue block and I'm tired of having to quick-
switch to lip-pursing when I want to pop an overblow.
  Please reply to me personally so as not to clutter Harp-L, and I promise
I'll post a summary of responses I receive.
