Hi, I´m not sure about the butt size of my shafts. I´m playing a titleist 990 dci with a dynamic gold r 300 shaft. Last time I regripped them, I put the Lamking Crossline standart grips (0.580) with a layer of soubled sized tape, but I think they are too small for my hands. I´d just like to know the butt size of this shaft because I think my hands size are between a midsize and a standart size. Should I use a 0.600 grips with a standart size or a 0.580 with 2 or 3 layers of tape? Thanks
