Serve receive: Imagine yourself doing that serve while the person is doing it. Extremely effective if you know how to serve it yourself.
Loops: Divide your technique clearly between looping backspin, top-spin and negligible spin balls, and differentiate them in your brain.
Footwork: still needs a lot of improvement. Lost a lot of matches today because I was trying it out, unsuccessfully. Need to integrate them fully into my game. A lot of the principles are the same as those of hand techniques, which includes a lot of pretension and release. Am starting to understand some of the basics.
Ready position: After every stroke it is very important to remember to return to ready position, deliberately, preferably with the bat pointing towards the opponent, to decrease the angles available to your opponents.
Blocks: Still have no instinct to block with the improved sidespin wiping block when the ball goes to the middle or to the shoulder(normally a shakehander grip weakness)
Chiquita backhand: Discovered how to increase power when dealing with short balls.
I usually lose a lot of games while adjusting to new techniques, but it's always worth it!
