It is obviously correct. You don't learn how to play on clay by practicing on wood, or ice. And you don't learn how to play on grass by practicing on clay.
The difficulties Borg had transitioning from clay to grass are legendary and demonstrate this. Yes, he won 5 Wimbledons and completed the FO-W double 3 times, but if you watch the documentary about him, amateur players who he practiced against in preparation for Wimbledon said that you wouldn't think he was a professional tennis player those first few days. Stuff like even missing balls.
Movement on clay and grass, for one thing, is completely different.
No, but if you only have one surface at your club. Clay would be the best choice.
