if you get the ones to absord shock then yes.... I get the ligtest ones I can find. Right now im using a Carbon Impact Quad which is light but absorbs vibration. Limbsavers makes quite a few

If you go to a shop, test them out by dropping them on there head on the counter. If they bounce they are no good. If they dont bounce then you know its absorbs shock

I dont shoot any better with or without one though if that helps answer you question
