Sounds like you want to do the cluck and moan sequence?
If so speed comes with repiticious practice as far as cutting notes off you will find the right spot when you use the reference words "Ick , aww , Ick , aww, Ick with voice inflection.
"Ick" produces the cluck and "aww" produces the moan....
Work on marrying the clucks on the front and back side of the moan to make it seamless which will give you the sound you are looking for.... . example "ick,aww,ick,aww,ick" ect
Make sure your on hand is correct for back pressure and your off hand for tone also be sure to use voice inflection to pop each note this will prevent hang ups..
Hope this helps...
