If you are ever intending to fly commercially do not even consider the wind-up method. It is difficult to relearn the opposite way, and in your CPL/ATPL General Nav course you will be taught wind-down. Some of the techniques are difficult and illogical wind-up, so you would be prone to errors. Of course in the classroom only one technique can be taught to the class, and this will be wind down.
In fact if taught correctly the wind-down method is no more difficult than wind-up, and makes more sense. Take the trouble to learn correctly now.
Best of luck - any problems drop me a line.
