I was introduced to over-sized grips 15 yrs. ago. I changed to the larger grips when my fingernails dug into my palm while I was playing. I liked the feeling of control and noticed my shot-making abilities increased. I have the larger grips on my driver and fairway metals. On my irons, I have the mid-sized grips with one extra wrap of tape. I would say to experiment with the sizes and wraps until it feels comfortable, produces the control that you are looking for, and doesn't create any additional problems. I'm working to find my draw and I think it is in the grip (and the swing).
