RE: VARIO
The answer to your question is yes you can.
BUT the next question is why would you want to learn on something that will cost you much more to repair, if there is enough left to repair, while you are learning.
The Vario is an excellent machine, but a good stable 30 sized would be the best to learn on.
The fact that Gravity Sucks is the one (and most likely the only one) that everyone that is registered on RR will agree to. We all started out the same way and it takes a lot of time a practice to make this look easy...
Good luck... (just my "humble" opinion)
