I agree that its just moisture that temporarily relaxed your sinew. No permanent damage done. I'm guessing you used skins that were dried? When you rehydrate them, they probably have more moisture than the fresh skins I use. I don't skin bows Very much so I would definitely listen to the wise words of Pappy and JW. Josh
Never mind me! Lol. I just reread your post and seen that you used fresh skins. I guess I didn't notice any relaxing of reflex when I've skinned em. I'm not saying that it didn't happen, only that I didn't notice.
