Well I finally have my demos in and will be taking them out tonight for an extensive test run. I am comparing the 08RDS001MP to the RDiS100MP. First off did some measurements against my current stick the Prince Diablo MP. All have a Pro Supex white overgrip and a Sampras O dampner: Diablo MP (stock) is 11.7oz and pwr rating of 1924 (per tennis.--- site) RDS 001MP is 12.05oz and pwr rating of 2005 RDiS 100MP is 12.0oz and pwr rating of 1956. The RDS001MP demo is strung with full NXT demo string at around mid. While the RDiS is with Head FXP and is loose--probably not even 50#! Looking fwd to my hit tonight. Am a little suprised at the high static wt, but the SW feels nice and very HL seems manuverable. I tell you what, they BOTH look outstanding and I love the longer grip shape! Would be fine with gaming either one of these sticks, so hopefully one will pull ahead and be the clear frontrunner! My wife is all on me about the mysterious UPS boxes always showing UP!
