Most everything I know about buzzbaits I learned from the BuzzBait King, 2Dogs! 8) You won't go wrong with the Yamamoto chrome blade, white skirt. Buy some Gammy trailer hooks and add one to your buzzbaits.
Make multiple casts to "fishy looking" spots, corners of pockets, big submerged boulders, etc.,. Sometimes you need to tick the big fellas off before they hit it. Stick with it and you'll have success!
Sam, I also like the Yamamoto with chrome blades and white/smoke skirt. And like Denny said, put a trailer hook on it (I use Gamakatsu). You can call Waterdog's and ask if they carry them or not, but if they don't, Yamamoto has their store on University just west of Price. If you're not sure how to put the trailer hook on, let me know and I'll show you the next time I see you at Saguaro.
