So I've been wondering; now that I have a collection of radicals, has the progression of technology really improved the racquets? Is it worth upgrading? Starting with the liquidmetal (earliest model I have) to the IG. I currently own up to the MG and have hit with the YT (although not recently) LM. .. .FXP . .. ... .MG . .. .YT. .. ....IG. 318g-->315g --> 312g --> 312g --> 320g 325sw->330sw -> 315sw-> 324sw-> 320sw 64stiff->63stiff->57stIff->59stiff-->62stiff 4 ------>2------>2------>2------->3 pts headlight Anyone else see a trend? It looks like the IG Rad MP is returning right back to where the LM left off at least spec wise. I know the material is different but I wonder if it's such a vast improvement.
