Re: Speed up the Courts
I haven't followed tennis enough many years to properly answer to this thread's question. But, from what I've read, grass is nowadays slower and clay maybe faster. The reason to this is that governing bodies want to make surfaces more similar and thus enable same players to succeed on all surfaces. To succeed on grass you almost have to be an all-rounder, old-school grass specialist can't anymore succeed on the slower grass. Having same players winning on each surface helps to create superstars, players who you can expect to win in whatever tournament on whatever surface, and superstars are what commercial rights holders want. Having different players succeeding on different surfaces makes tennis more difficult to market. Also, more similar surfaces make achieving GS a bit easier, and player achieving GS, or even playing for it in USO, will bring much extra publicity for tennis.
I'd personally prefer more variety in court speeds, achieving GS with a win at ultra-fast Wimbledon and ultra-slow RG would be a really respectable achievement.
