Doesn't really matter if smashing is powerful or not. When I'm playing against many players in a couple opens before. I'm smashing left right and to the front. All my opponents have time for is to run and lift. What's more important than the power of the smash is the control. If you can learn to control a smash it's a lot more powerful than a powerful smash. Though it be nice to have both. Control to smash it near the front and not in the back is a much harder task so when i started to train smash I started to train left right to the back and then eventually it got faster and stronger and then I could smash to the front. So I guess what i'm trying to say is. Practice smash control and your smashing will become more powerful as you learn to control it better.
