The microgel prestige pro has a strung weight of 343g and at 7pts HL. The swingweight is 316g. Also, MG radical pro has a strung weight of 332g at 4pts HL for a swingweight of 319g. Others to compare: Kinetic pro 5g, strung weight of 332g at 8pts HL, for a swingweight of 318g. Ionic Ki 5, strung weight of 335g at 7pts HL for a swingweight of 325g. The two microgel racquets seem to have exceptionally low swingweights compared to the PK ones, given their strung weight and balance. ( you'd think a high strung weight and less headlightness should lead to a higher swingweight, right?) Why is this?
