Can I get of list of rackets manufactuered in the past 5 years that are above 11 ounces, considered high end tweener/player frames that pack a good deal of inherent power? I know that power is largely dependent on the player and whatnot, but I'm just asking for rackets that you considered inherently powerful. I'm just curious to see what turns up (ex. I never thought the O3 Hybrid Tour would be considered powerful). So far, my list is at: Pure Drive (cortex, and non cortex) Aeropro Drive (cortex, and non cortex) Pure Drive Roddick O3 Hybrid Tour Microgel Extreme Anything else?
