Vises are only a Device to hold Hooks whilst Tying Flies & it doesn't matter which one you have the job still gets done,they all have their +s & -s regardless of cost.
I had a Dyna King Vise,like Rick I also bought The Atlas which I've now used to tie hundreds of Flies,there were a few problems with it at first & the machining was a bit rough so I fixed the problems,also I installed a Small washer in front of The "O" Ring on The Back End of The Vice to protect The "O" Ring.
