Hi Art -
W/o a doubt the surgeons is stronger than the blood, but I don't seem to have blood knot failures and I like the streamlined profile better. I think the tightening sequence is critical for strength of the knot.
For a terminal knot I always use a palomar even though it eats tippet. It's an incredibly strong knot and there's nothing wrong with replacing the tippet often anyway IMHO.
Keep us posted when those hardtails start bustin' down your way Art!
