that works. also learn or practice pressure on the call and adjusting air flow to change the sounds of the call. practice whenever you can. when you have a big tom all balled up and strutting at 12 yards ready to kick the snot out of your decoy, you'll realize then what it's all about.
some people gag, some people get tickled by them, some people have no problem with them. i have no issues with them. those domes do not work for me at all.
