I'm going to buy a Boo string, that is a fact (if Don wanna make it for me

I got a good STS (matthias V-bar), so that lowers the sound of the bow quite alot. The question is it overkill to get whiskers also? Or do you think: "Why not get them, always nice with a quiet bow"? Or will the fps loss damage the bows performance more than the actual "happiness gain" by the lowering of noise.
What do you think. I guess you all have thoughts on it.
