I have been shooting the Simms 3 piece stablizer on my Parker feather mag II for about 2 weeks. The Parker has a little hand shock and the Simms helped but at about 45.00, I would have expected more. Don't get me wrong, It is a good stablizer and looks good with the camo which is very well done. After putting lock tite on the threads of all three sections, they stopped coming loose. I will continue to shoot it until I can personally shoot something better as I can't afford to buy just to try. I would appricate any suggestions of ones to try. Don
