The post about spin prompts this observation/question: Some racquets I test just seem to be created for serving. They usually have open string patterns, generously head light, with swingweights somewhere below 320 grams with total weight somewhere around 11.5 to 12 oz. My experience is they just seem to snap over the top on their own naturally. Anyone else notice this? Would adding weight to the buttcap of a racquet with an already-high swingweight promote this effect or just make the whole racquet slower on every shot?
