when I throw...

When I throw a hard throw the string always seems to go to the edge of the bearing, when I throw a soft throw it is dead center, how do I correct this?

practice, when you throw it soft you have good form, but when you try and throw it hard you are loosing your form to get speed.

ditto, one thing you could do to practice your throw and work a few other things as well is to throw a sleeper, bind, throw breakaway, trapeze, brother of trapeze, dave bind, repeat. I do that all the time I do it until I get bored a lot of times when I don’t really feel like working on a trick because I have gotten frustrated. It helps you get a lot of things down.
