Hello Frank
Over the last few years I have found essentially the same thing you're saying as I have only had stabilizers on for any noise left over. I have used the S Coil since it came out and at 5 oz it is perfect for me on all my bows. I dont need that 5 oz for balance or stabilization. Mind you, I am not on the tourneytrail and I am a bowhunter first and foremost. If I had a fancy rig for spots or whatever I can see maybe the need for one.
I am perfectly happy with the SCoil and can effectively shoot the animals where I want DRT.
