Yea its weird, I mean I get people have different techniques, pancake serves, weird swing motions and all, nothing weird to me about that.My nemesis in 4.0 singles tournaments had an even weirder racquet prep, but without the dance moves. Think Goose flapping wings ... and two or three pre-flaps before going into trophy position. His entire game was homegrown unorthodox, but tough to beat ... he won some 4.0 tournaments. I refused to move to 4.5 until I beat him in a 4.0 tournament ... that was a glorious day. That is what I mean with you getting value from lower level tournaments. It's a rite of passage paying your dues thing.
lol ... one day I saw a lady playing tennis that I immediately knew was this guy's wife. I had never seen her before ... but she was flapping like crazy.
But I don't get why some people have some really weird moves like dancing or hopping or rotating in weird ways and flappin wings and so, what the heck lol, why?
