Yes, the toughest part is staying with the exact same setup, but that does work wonders, especially when you cant play every day for 4-5 hours a day.
I learned tennis at an early age and had 1 prince racquet and the same string and tension for years. So that really helped me out back then.
One the best things that helped me put together a lot of the concepts on the LnR site I mention and relaxed play in general was watching pros practicing in person. If you ever can do that, it will make a huge difference. Being right next to them while they are warming up and not playing at full bore in a match really slows things down and helps you visualize it better.
