4000 is fine, but you can get a sharper edge by stropping afterwards. It’s cheaper than adding another stone to your arsenal. Next time you are placing a Lee Valley order, make sure to drop a green polishing compound bar ($10) into your cart. Rub it like a crayon on some MDF (or leather glued to a substrate) and use like a stone (except only with backward strokes). One bar will last you a lifetime.
