I've been interested in purchasing an older (LM or MG) Radical and slapping a leather grip and some CAP grommets on it. A couple of questions for those of you who know how to calculate specs. Let's take the MG specs, for starters: Midplus Specs Head Size: 98 sq. in. / 632 sq. cm. Length: 27 inches / 69 cm Strung Weight: 11oz / 312g Balance: 2pts Head Light Swingweight: 315 Stiffness: 57 Beam Width: 21 mm Straight Beam Composition: Microgel / Graphite Power Level: Low Swing Speed: Fast Grip Type: HydroSorb String Pattern: 18 Mains / 20 Crosses Mains skip: 9T,8H,10H Two Piece No shared holes String Tension: 52-62 pounds With a leather grip, I know it will affect the static weight and balance. Will it alter the swing weight? If so, by how much? Now, assuming I've added a leather grip, how would the specs change if I were to install CAPs (static weight, balance, swing weight)? I appreciate any answers. I know several of you have carried out these same modifications to Radicals, and I hope you'll be able to help. I'm far from a customization wizard .
