Learning to Juggle 5

I've been trying to learn to juggle 5 balls for several months now. I only practice Thursday nights for a few hours at our (TurksHeadJugglers) club meetings, so it is definitely my fault that I'm not progressing faster then I should.

I'm finding that using tetrahedral felt bags filled with shot seems easier then my Dube balls.

I've gotten to the point where I can flash 5 fairly consistently, 6 once in a while, and 7 once in a GREAT while.

My biggest issue is accuracy. I juggle facing a wall and with a large pile of gym mats in front of me so I don't have to bend over to the floor every 15 seconds or so to pick up the bags. When I'm tossing 3 or 4, my accuracy isn't bad, but as I throw higher and faster, it goes to pot. Tosses from my Right hand inevitably go forward, so if the wall wasn't there, I'd be walking forward, and tosses from my left go much higher then they're supposed to. Every so often I just back down to 1 or 2 balls to improve my aim. It is going much slower then I'd hoped though.
