Disc brakes feel spongy no matter how much I bleed them

I appreciate all the comments. I am using dot 3 fluid, yes I am used to manual disc brakes, I did a good bench bleed, I have replaced all 3 rubber hoses etc. I will try today to block off the master then the rears then bleed the front again to see if I can nail down the problem. I have the stock master and did not take the master apart to verify the size of the bore but it may come to that.
