I am currently looking at two rackets. Head Microgel Prestige Pro & Volkl Power Bridge 10 Mid. Prestige Pro weighs 12.1 oz, 7 pt HL with the swing weight of 316. Volkl weighs 12.1 oz, 10 pt HL with the swing weight of 337. With the same weight, shouldn't the one with a higher HL balance point have lighter swing weight? But if you look at the above two rackets, the results are the opposite. Can you explain why? Thanks.
