I too have had a Norvise for 3 -4 years and I have the in line jaws which it can with. I have tyed hooks from a size 2 to 20 with it. The jaws seem to hold the hooks sufficiently. The Norvise is my everyday tying vise and seems to work fine. I have found that in some cases on larger hooks, where I tend to put more pressure on the thread when tying, it requires a little more adjusting of the vise jaws to hold the hook firmly. Prior to purchasing the Norvise, I used a Regal for larger flies. The Regal has superior large hook holding ability in my opinion but does not have the rotary feature. I still use it for some tying. For smaller flies I had the Renzetti Traveler. I use to tye size 8 - 20 hooks on it. Since I have gotten my Norvise I have not used it and feel the Norvise is far superior to the Traveler.
