Training for a Tournament...

So I have been given the go ahead to train for the All Women's Championship Tournament in Kalamazoo, Michigan in November. It will be my first shiai and I am excited. For now I am practicing judo twice a week (the maximum available around here) and conditioning in my off days. I want to lose 15 more pounds and get a little bit stronger. As far as technique goes??? I am pretty good on the ground. I can consistantly get several different hold downs against the guys in our class, and my armbars are coming along with practice during newaza randori. But my throws...eh...need a lot more training there. I am not a natural by any means when it comes to throws. My grip strength is improving though...although my husband says I am getting "man hands". A hazard of the sport I guess.... I am just going as often as I can and trying to focus when I am there.
