Does string tension affect a kick serve ? Is the higher the tension, the more spin and speed it has ? And should i go get a yonex rds 001 ? lmfao i have a aerodrive and thinking about switching x] I use a 52 tension and use the kick. But when i use a racket with 59 tension , my kick turns more to the left almost like a twist serve and it is so much faster. Am i just imagining it or does it really affect the serve ?
