The Speed Flyer looks like a pedal I would definitely use (if I wasn't already happy with my Tama Speed Cobra). Pedals have improved so much in the past 25 years, everyone is making great pedals now it seems.
I know some of you like the Speed King, but just watching Carter play it I can tell it's not for me. It definitely has less power and a "stiffer" action. Too old fashioned for my taste.
