I don't think it matters what your basic trainer is, (as long as you can fit comfortably) much more important to have a good instructor that you can get on with, and to fly regularly. It will help if you fly close to home, if that's at all possible. Turn up on time for your lessons, having prepared by reading about the exercises you intend to fly. If you have questions, please ask your instructor for help. You can make notes at home if you think you might forget what you want to ask. Pprune is a great place, but face to face is even better. When you get to flying crosscountry, you might want to take a short holiday with a booking or two every day to make the most of weather slots....
Enjoy!
