Motorboaters: I have a pretty shallow gag reflex too - so to get a good purr, I cut a little off the back (careful not totrim so much that you lose your seal), then I kinda turn it a little bit to the side, and roll my tongue over it.

You kinda have to cup your tongue and just roll the tip of it over the reeds. I have this technique where I kinda just roll the left half of my tongue, and pin the call down with the right half. That's why I turn the call a little bit sideways.

Yes, this is a conversation between men about the depth of our gag reflexes and how long our tongues are . . .
