Thanks everyone for the input. Daddy Rat you are correct you need to trim just small amounts at first in my experience. MK my plan is to come up with a template once I find the right fit. I have issues with the tape bunching up around the front of my teeth, I believe mine will be egg shaped as well. GunRunner thanks for the input I look at the youth calls and have bought a few, I found I have trouble holding them in place. Thanks everyone for taking the time to comment on my post I hope everyone has a successful year this year.
