Same comments here. I had owned one of the original Tranquilizers shortly after it came out and I felt that it did wonders for noise and vibration. It was a little too light to really add any forward balance to the bow but I see that the new models are now tapped to accept weights/accessories.

I also recently picked up a Tranquilizer shorty to use in conjuction with a Sims Enhancer 2000 on my Patriot SC but have not had the opportunity to install them yet.
