I'm fortunate enough to have access to both clay and hard courts at my new club. Until 3 months ago, I had practiced/played on clay no more than 10 times in over 4 years of tennis. For the first 6 weeks I played only on clay, to which I had a pretty hard time adapting. Only now I feel comfortable, notwithstanding the hard time trying to develop S&V. I have played mostly on clay, but have been switching a lot lately. The thing is that I feel my game is being a little disrupted by the clay to hard to clay to hard... back and forth. Do you think there is logic to this reasoning? What would you suggest I do: one week/month/... on clay and the other on hard or is it actually better to play one day on clay, the other on hard?
