it is a great vise for sure, being able to tie flies uber fast, but when i was going to to get the nor-vise the only thing that stopped me was not the price tag the fact that you need a speacial bobbin. for this you cannot change your thread on one bobbin but since i have 15 threads i tie with i would have to get 15 bobbins. i would find this a pain in the arse and costly just for bobbins.
Hope this helps
