I have the original Traveler with the screw lock jaws. It's a good and very popular vise. I never saw the need to switch over to the cam jaws as the vise worked fine as is. I now use an HMH Spartan since the more traditional design of this vise gives me better wing access for tying wet flies. Unless you are interested in true rotary tying, I think the HMH is a better vise. But you will do well with either one.
