I have a shock blocker 1000 on my ar34 ram cam and a half. I can tell a difference with mine when i shoot and a little on the vibration side not much. I notice i do shoot better with it on and i was told it would reduce string slap which i dont know bout that. My bow doesnt have much vibration and i imagine with your matthews you have the same as mine or prob less. For the money i think its worth it. I may hop mine up next year to see if i can tell a bigger difference. So far im happy with mine.
