I have been hit on three different occasions/games on my Unequal CP during JUCO Fall Ball so far. One was a ball that glanced off the bat and into my upper chest region, one off my shoulder, which hit the plastic and lastly...one where the catcher got crossed up by the pitcher, barely getting his catcher's mitt on the ball and striking me pretty square in the chest. I will say that the ball that hit the plastic on my shoulder was no different than getting hit on my West Vest...loud noise, but didn't feel a thing. Having said that, I am still evaluating the Unequal.
As Texas Manny so eloquently stated above, "Kevlar is meant to absorb the shock and disperse the impact across the plate (I too was also in the military)..." I did "feel" the hits to the chest and I do remember being surprised, especially the pitch what crossed up the catcher. I'm not exactly sure how to explain it, but after initial impact, there was a slight sting but that dissipated almost as fast as it happened. There were no lingering feelings during the remainder of my games; meaning, I wasn't gun shy whatsoever, and I experienced no tenderness or bruising the next day. In fact, I can confidently state I did not wake up the next morning feeling/knowing that I got hit with the ball.
The reason I say I'm still evaluating the Unequal is because I believe you will feel the initial hit/shock/sting from the ball; just like I did. The question for each of you is whether that initial shock is worth it. If you do not feel any pain from any ball off your current CP, then I would say stick with it; because you will feel something with the Unequal. mstaylor has some wise words when he stated: "don't get rid of your "good" CP until you know you like the new one!"
Hope this helps.
