It's a good idea to get your fitting done right now. And since many fitters are also coaches with some knowledge of biomechanics and kinesiology, you can also get some suggestions to develop a fluid, 360-spin.
I envy your starting out, because I never bothered doing these things when younger and had to spend years hammering with lousy form and fitment, then a few more years unlearning bad habits.
Good luck and let us know how it goes!
