My new groud pounder!!!!!

Hey guys new to the sight,I have a question on rod choice with these 470s..Which rod did you guys go with the 6.76 or 6.535..I went with the 6.535 just because I didn't care for the idea of the oil support ring or custom Pistons and I know with the 6.53 you get a little more side load on the walls.Are any of you guys running the 6.535 rod?
