how do i become a confident, and comfortable with my handles and what are some drills that can help especially the weak hand and dribble moves
Practice with two balls at the same time, might be tough at first but you will get better, also might try a product like the Power Dribble, I have used in past and really works. www.powerdribble.com is thier site and is a great tool.
hope it helps
Not much to say honestly just practice, practice, practice..
