    Yes, they still make it and some guys still use it.

    I just talked with the boss about 77 the other day. He still loves it, says it's the best for a long hard pull. I've had better luck with Aqua Gel and it is much easier to clean up. 77 looks like puke & is hard to clean up. It gunks pipe up too & makes future removal of wire much harder.
    Yes, I'll be happy to do a first class job for less than anyone else and take a dollar a week for 10 years.

      Like was said, you really don't need to use an separate EGC here at all, but many of us do because you don't want to rely just on the conduit. Though there is no reason not to, it's a matter of choice. So you are going to have to make up your mind. If you want a separate EGC I would remove the #12 and replace it with a #10 because a separate EGC says you aren't relying on the conduit. But if doing so exceeds the allowable fill then just remove the #12. Will make pulling easier anyway.

      I would use the green as a pull wire for my new conductors.

        Our guys used to call 77 “baby s**t”.

            works with underground runs, not so well with a run that runs up, horizontal, then down again.

              The OP asked about fill calculation. The fact that he indicates he is a master electrician and does not know how to do this is concerning.
              As far as determining any derating, I don't see how any comments can be made with out knowing the facts about the type and size of the loads connected.
