Are there any tutorial videos on the internet that explain how to throw pitches with an unscuffed wiffleball?

I've been playing with this technique since last fall when I entered into a wiffleball tournament and the rules forbid us to use scuffed wiflleballs. I saw other pitchers throwing risers and sinkers with brand new balls! I accidently learned how to pitch the sinker in that tournament out of desperation to remain competitive. It was too late however. I pitched four scoreless innings before giving up a homerun and the game. I've learned the knuckleball, a sharp curve, and yes, the sinker. I can throw the screwball too but I can't control it. I'm planning on making a video soon but I'm not ready to do so until I get all my pitches down.Are there any tutorial videos on the internet that explain how to throw pitches with an unscuffed wiffleball?
