#3 is best of the group, but I'm guessing it's the reed configuration that makes the difference. DON'T fall into the trap of trying to run before you can walk - if you know what I mean. Master the basic yelp 1st. Don't get distracted by wanting to cut, cackle, putt etc. while your learning the mechanics of air flow. That will drive you nuts! Like Guesswho said... S L O W down on the cadence. All 3 still sound like there's an air seal / tongue pressure issue (that's the hardest hurdle).
Work on getting a good seal, good fit, clean yelp. Clean can be raspy, it just means the air flow is directed across the reeds and not all around them. You're almost there...good luck!!
