Trained a similar amount of time without giving it any thought, mostly curious as to whether other people experiment with it at all since that question from my friend caught me off guard.
As for pulling the same way each time, it really doesn't feel any different to switch. I don't really know turn my left palm around besides doing it that way the very first time I felt the need to. That said, I would definitely prefer to stick to it for the very heaviest sets.
