Am I mistaken or does 18x20 give more spin? I really thought 16x19, the more open pattern gave more spin but I am not so sure anymore. Let me explain, I have been using 16x19 (Dunlop 300g) for a year, but right now I have an 18x20 (LM Prestige MP) demo. Crikey but the Prestige gives more spin - or am I imagining things? The Prestige is great at groundstroking, big hard shots with lots of control. However I was playing doubles today and got great spin out of the devil. If not stringbed, could swingwieght cause better spin? This demo was also strung real loose, perhaps that added spin?
