I've been playing with the Volkl V1 Classic recently and with other Volkl models prior to that. I love the comfort and maneuverability of the V1 (and all Volkls I've tried). But, as I've aged and slowed, I'm feeling the need for a little more power assist from my racquet--possibly going to a 105 head size. I would appreciate some feedback/advice on something to meet that need in the Volkl line preferably, or other lines that offer the same comfort and maneuverability. Thanks much.
