All my deer hunting anymore is from stand and all have been double lung broad side, a few have been single lung with how high I like to go and how close I let the deer come. So all my arrows are stuck in ground within I would say a ten foot circle of where I shoot so finding my arrow has never been a problem for me. If you shoot from the ground and your arrow may fly ten yards or so after the shoot then it may be worth it, but I like smoke have not seen the need. I have never lost a arrow, but this year Awshucks has posted some about cresting your arrows so I am going to be doing that so I should never have any trouble I hope. It seems like I also remember the CB beating them up real bad and they did not last long, seems like there was someone on here when they first cam out and that was what he said. They may have improved them.
