The reminders as they have been called since the 40's are very minor and will not stop you from gripping the club in any orientation you wish, they are called reminders as it's just a very small ridge which gives people peace of mind they are gripping in the same place every timeAs said in another thread connected to this one. It's the way I was taught.
I stand by what I said though round are they way to go if you want open /close the club face. Not only for fades and draws but also for changing the club face when it comes to wedge shots.
A ribbed grip will only let you grip the club in one position (unless you make absulutely sure you do not let go of the grip with your left hand) and for me if the grip has been put on square it means a closed club face in my hands . We all have different hands and a ribbed grip for someone else may mean the club face is square
