Sorry! I haven't had a chance to reply to anything this week, crazy busy! See my answers above.
I've been practicing my own throwing (with Ozzy, because he can actually catch them ) instead of trying to throw differently with a dog who's inexperienced. I'm just now learning the forehand throw and the disc is all over the freaking place lol. With the backhand I can use my arm or my wrist to snap it out, and they generally go exactly where I want them to go. I'll definitely have to practice getting the disc to hover. I know it can be done because I've done it unintentionally, I suppose it's also just a matter of practice.
I'm going to keep making Oz fetch them though lol, it's easier than running out to fetch the disc myself every time, though that might be a sufficient motivator for me to get it right, hahaha
