How tight is your bow?

I have a great nurnberger its one made by his son but still my prized possesion since im poor the bow needs a rehair badly I think the hair has been on for about ten years & rather than breaking lots of hairs it's just so smooth it won't grab no matter how much rosin you put on (I'm sure pops would work). Where do you guys get your bows rehaired? Also Ken what style bow do you use?
