Rochester, I have a Dan vise and now I wonder how I ever got along without it.

As far as why I use the rotary, it would be for all the activites I was previously doing without the rotary feature, they are just a whole lot easier now.

I use it for head cementing, palmering, tying in beards or throats, and just plain getting a better look at the fly. As well as reasons I can't right now remember, I am sure.

Some say it makes no differance and they are right when they say you can tie any fly without it. I do believe it makes tying a whole lot easier.

As far as the quality of my flies, I do find that my palmered flies have nicly spaced hackle wraps more so than before.

I would say keep the Dan vise. But thats just me . -Yaf
