Should i take field hockey lessons this summer or tennis lessons? I need to choose one, because i want to sign up for one of them in highschool. (going into 9th grade) which is better to take and why?

i’ve been playing volleyball for 3-4 years and i’m pretty good. my best point is passing/bumping. the thing is, i’m REALLY short which probably isn’t going to fly very well with the highschool coaches next year and the only real chance is for me to be a libero. so, i was thinking of tennis lessons because your height doesn’t matter in tennis. are the two sports alike? can i use my volleyball serve to help a tennis serve?
