th_up or this one

similar grips to the 7-2 paddles. really easy to hold. pricey but if it makes the different its worth it. paddle wax also helps grip with a relaxed hand (IME).

(BTW-I use a zero degree paddle too. The way I think of it is that whichever hand is forward is the lead/control hand. so 1/2 the time you'll need to grip w your bad hand.)

good luck!!
