They have their advantages, but don't forget their disadvantages, the simple inability to create spin. Look at how WMY is handling Batra with a simple push/loop cycle or a continuous attack if blocks are poor quality. Batra can't attack a push to her BH side, and she can't attack a spinny loop even if it's too high either as long as it's not short, and that's a big disadvantage, the reason these rubbers are not mainstream.See that's what's stupid. preparing for LP or antispin is a full time job. You would need months of preparation and training to really understand every detail of how the rubber responds. But they may face 20 different players. There's no way to prepare for every version of unusual rubber. Fundamentally the demand is just unfair.
