Hi, After playing tennis for about 4 years, my coach is now trying to teach me to face the butt cap of the racquet towards the tennis ball. I am having a hard time trying to do that. So I have several questions. 1. I've seen several tennis players do the same thing, so I think that technique is correct. Do you have any tips to help me master that stroke ? 2. I currently play with a Dunlop 4D 200, as you know it is a heavy racquet (11.9 oz) with a high swingweight (337). I was wondering if another racquet would help me. I was considering Dunlop Biomimetic 200 lite or Head Youtek Prestige midplus as they both have less swingweight. Thanks for your help, Sebastian.
