I certainly want to avoid raining on anyone's parade, but I feel compelled to point out that BPI says that the 777 formula posted on Ed Buffaloe's website is wrong. BPI's price is pretty dear (although again, to be fair, you get years worth of developer in a 4 gallon case, which costs <$60 including shipping), but I consider 400TMax developed in 777 to be the closest thing we'll find to the Photographic Philosopher's Stone.

I consider 777 an unfair advantage over any of them, when used with 400TMax, the best B&W film manufactured today.
If you want to effortlessly make negatives which will easily produce glowing prints, BPI's product represents the better part of valor. Do yourself a favor and don't screw around. I don't know if the BPI formula is the original Defender 777 or not, but it's so good that I don't really care. In any case, since it's still available and according to BPI in constantly heavy demand, why experiment? They'll continue to manufacture it as long as we continue to buy it.
