I know that different grip materials (silver wire of various gauges, silk thread with various alloying metals, imitation whalebone, etc.) have varying weights and affect the stick's balance point. When I recently had my bow regripped, I talked for a good long while with the bowmaker (actually, it was more like I listened to him talk, because he actually knew something) about wrap options, their weights, overall bow weight, hair quantity/weight, and tip weighting to compensate for various options.
All to say that if you are changing grip materials/weights you may affect the bow's balance point/feel. If you are replacing something with the exact same stuff, disregard the above...
