You will probably get answers from Instructors as well (I hope!!), but here is what I've learned: as a student, do not change the reserveprocedure you've learned.
You will only get confused and you're bound to make mistakes up there; not very advisable.
I read a story once of a student that came back to the skies after some 10 years or so. He claimed to have forgotten his former reserveprocedure. He learned a new one. But some time later, when he decided to do a cutaway, he flawlessly went to back to what he had learned at his first course!
Apparently, what has once been drilled into you, somehow sticks in you as sort of a muscle memory thing.
Now I know that there are some instances that you HAVE to change procedure (e.g. tandemmasters), but as a general rule I'd say; stick to what is already there in your mind; you'll be safer that way. (even if a cutaway takes a little more time than it might have done had you used the other method.)
B safe!
