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
A warm summers rain falls down on a quiet fishing stream
Lined with cabins, smoke straight to the sky
Two ol fishin buddies with never a care
Teasing a trout with a fly.
