    338 Edge Load Information

    Specifically about the Edge, but Shawn has reported good things about H1000 in terms of temp sensitivity...
    cost is likely a bit of velocity.

    H-1000 is my choice too. It also seems to burn cleaner than the Retumbo i tried first.

    Retumbo or H1000. I use both equally.
