A simms enhancer 2000 with a carbon impact fat boy filled with silicone and limb saver on the end of it, and a quick disconnect in between the enhancer and the carbon impact. The whole combo is 12" long and weighs 1 lb. It cost a tad over $100 for all of it. It is like shooting a completely different bow with it it and the limbsavers installed. It balances my bow perfectly in my hand also.

But like Len said, every bow and every person is different. The best thing do is go somewhere that will let you try different ones out to wich ones work best. I tried a doinker when I first bought my bow and it did nothing for my bow. I also tried to put my same combo on an Ultra light 31 and it was horribly out of balance, but the enhancer 2000 alone worked perfect.
