My Nor-vise is a wonderful thing!! I love it. You gotta get one.
I bought the midge jaws very shortly after the inital purchase and would suggest that you do the same. I found that I was used to the angled jaws of a previous vise and found it difficult to tie small flys with the straight jaws (big fingers). I now tie all sizes on the midge jaws including salt water flys. I found that the small arm supplied with the jaws centers the jaws well enough so the jaws "spin" very nearly as well as the straight jaws and you can do all the neet things in the video.
Don't buy the travel pack. A base is easily made fron $2.00 worth of shelving material found at Home Depot.
I bought the bobbin but if I could do it again I wouldn't buy it. It is difficult to get used to and very hard to change thread. I think that I would buy the Ekich Bobbin (An FAOL Sponsor) if I could do it again. It looks like the "trick" way to go.
