dropper fly rig

On my recent trip to Idaho I fished a tiny nymph under a dry, some each day,
as the fish were obviously taking baetis nymphs not the duns or emergers.

Like most of us I've used this technique a lot to good success, but unlike
those of you that actually know what you are doing, I'm not sure how best to
attach the dropper nymph. I've always just used a clinch knot around the
bend of the hook

This trip I had several breaks offs, with small fish at that, where the
break occurred at the cinch knot on the bend. .... ANYway, what do you real
nympher guys use in the way of knots for dropper rigs? In the wind, with
cold fingers, and weak eyesight knots are proving to be a steady source of
frustration for me :-( and I need to improve my knotting skills
