When I was looking at getting the Standard or the Spartan the difference seemed slim so I went with the cheaper Spartan.At first i liked the vise it is solid and will last forever. but on mine the whole head would move when i would lock in the hook no matter how much i would try and tighten the hex head bolt it would slip. Also as my tying would progress and i found myself wanting to tie more rotary the vise just fell short. All i use my HMH Spartan for now days is for tube fly's. This is just one mans opinion but if you are going to spend the money for a Standard look around there are better ones out there for the price.
