Stick with the LS 2 holder on my NXGs or upgrade to the Edge?  Long story short, my right LS Fusion runner is bowed. I had the shop straighten it out as good as they could but it's not perfect. I need to get new steel but am concerned that the right holder may be part of the issue with the bending. Upgrade to the edge with new runners or just new runners on the LS 2?
