When it comes to LaCroy products I have been a heavy TE user, I am getting way too curious about NPA though. I know its bascially the same product just 4x times as concentrated as TE but still I am human and I am wondering if any of the guys have had better or more heightened results with NPA opposed to TE? I am just wondering if its worth it. I already stocked up a bit on my SOE but if its not I will just buy more SOE, ahhh thanks.
