I got my limbsaver ultra quads and my mini limbsavers yesterday. I mounted everything last night after taking off my ugly OEM Bowtech Tribute silencing kit. From the VERY FIRST SHOT what an incredible difference, SILENCE AND NO VIBRATION WHATSOEVER, NNNNNONE. It was absolutely amazing that is the ONLY way I can descibe what it felt like to shoot, at least on this forum anyway HAHA. ALSO from a previous post. I found that on my 30 yard shots that I was having problems with is because I was actually shooting about 40 yds. My friends father hunts religiously and he marked the true yardage 10/20/30 and I had 90% VERY WELL placed kill shots today. I will continue to practice so ALLLLLL my shots are PERFECTLY placed kill shots. What an exciting day.
