Here are a set of UOAs I had been meaning to post. Installed a true bypass oil filter at 56820 so its been in use this whole past oil change. Looks like it has brought the Fe and Al down a bit.
I have not changed the oil at this point in time since installing the bypass. I considering going another 7600. If so I will change the normal oil filter.
