Grips on a TM R580XD

I have recently purchased a TM R580XD (very sweet) but I am not overly impressed with the grip on it.....too small for my hand. I have Lamkin perma-soft wraps on my irons and fairway woods and love them. I have heard that the R580 line requires special grips due to the shaft.....does anyone have further info?

I honestly don't know. Some of the taylor made grips have a .680 core. Best place to ask is Golfsmith's clubmaker's forum.
