WOW, every time?

I just don't experience the speed reductions that are always supposed to happen with things like tubed peep sights, string silencers, etc. My bow shoots the exact same speed post adding a rubber tube and peep and I was told it would slow it down 3-5 fps. Not that it would make any difference anyway, but I doubt adding a kisser would make any recognizable difference. If you think it would make you more consistent, use it.
