Stabilizers matter more with older bows with a lot of forward recoil. Paralell limbs recoil up and down and shoot dead in the hand, so it's a lot easier to properly hold the bow (you're not worrying about dropping the bow or getting slammed in the back of the hand by the overdraw when you release). There's less torque on the bow when your bow hand is in proper position and relaxed. That being said, I put a small sims stabilizer on my Maxxis 31 just to help balance the bow in my hand. The stabilizer will mute small errors you have in your grip form, but it is not necessary on newer bows when your shooting form is perfect.
