How do you usually return serves? Do you take a crack/swing at it, or do you block it back?

With faster flat serves, try to meet the ball and take advantage of the pace to block it back. If you take a swing at it, you may find yourself late more often than not. Like you've already mentioned.

For high kickers, make up your mind whether you want to take it early, before it gets too high for you to make contact. Or step back and let it fall back down to your contact. Never in-between. I personally like to take it early and not lose court position if I can help it.
