well, ive tied for years on standard vices that supposed to hold the hook, some a bit better than others.. wanted something better that i could tie a veriety of flies as well as sizes so i tried a few different rotary vices.. after testing some i decided on the danvise because of the rotary function and its price.. very sturdy vice & the rotary function of it allows ya to make more smoother fly bodies.. the only drawback on the danvise is that if you dont adjust the jaws correctly you could chip or break them, so the directions say.. jaws have a lifetime guarentee.. i havent had any trouble out of it yet & ive tied about 800 flies on it as of now in the 3 months that ive had it..
