How important is the continental grip for serve + volley for a weekend player
I'm 24 and have been playing tennis for about 2 years. Recently I have been getting some coaching and while it has helped improve my forehand and backhand it has destroyed my serve and volley. My coach has me using the continental grip for serves and volleys, which I have never used before and it's making tennis much harder for me. If I see a ball drop short I panic trying to switch to this new grip and usually end up hitting the ball into the net, or somewhere completely unintended.
Normally I hit my forehands and volleys with a semi-western grip and serve with a semi-western or eastern grip. I can usually whack the 1st serve pretty hard and have decent consistency with this. It's absolutely useless as soon as I try to hit it with a continental grip.
I don't plan on reaching a very high level of tennis so should I just flag the continental grip altogether and have fun or grind it out until it feels more natural. I get the feeling that I will probably never be able to exploit the full benefits of the continental grip making little difference to my game even after I get used to it...
