Depends on what you mean by grooves. There are bevels (8, usually) that run down the length of the handle, parallel to one another. Those are best felt with a leath grip, yes. Or, you could just use two overgrips, and no replacement grip.
There are also grips that have a groove that spirals down the handle, and have nothing to do with bevels. If this is what you are talking about, there are a number of grips that have this feature. Look for the word contour.
