Like i said, I've never experiened any difference in speed with them and we all know about suggestive advertising. For most people, if they tell you it will make your bow shoot faster, you put it on and all of a sudden you're bow is smokin fast now. It's all in the head. The product has other benefits, but chrono your bow with and without the thing on there - there's not a speed benefit with the product.
It will depend on what slide you are replacing. In my opinion it is the best slide out there. It does not get sticky in different conditions. I actually se a coat of teflon left on my cable guard after awhile. Maybe that will make it faster over time but doubt it.
Oh...and this is what is posted on the SIMS web site:
Made of pure virgin Teflon®, the Sims Cable Slide made for a 3/8” cable guard, produces an ultra-quiet shot, extends bus cable life and virtually eliminates the chatter from a wet cable guard. In some cases, increased speed has been reported.
