I love the restaurants on Taylor St. - particularly Francesca's. Good French place around there too but the name escapes me. When my son's in town, we wind up eating alot at John's Polish stand on Roosevelt just off the Edens.

Basically, it's the same deal as Normand described. Maybe a little harder but maybe a little more secure. Just open the shot and push the knot open. I fish the Driftless alot and it works fine although to be honest, most of the time when I nymph (and I most definitely don't nymph most of the time), I just clamp the shot right above the tippet knot. If I lose it, I just add another.
