One more vote for the Bend knot tied with Hemostats. I switched to this for everything but loop knots about three years ago and I cant't tell you the amount of grief and animosity it has saved me. I can honestly say I have never lost a fish because of knot failure since making the switch. For loop knots the Davey is the way to go and for blood knots/surgeons Orvis has a great tutorial on how to tie a joining knot with Hemos as simple as this one.

When the Eugene bend cinches down you feel it pop when it turns over and you can feel confident is is fully tight at that point.

old eyes make getting the tippet into the fly a pain but with hemos no need to make knots a big deal.
