X-spert? Isn't that a has been drip under pressure? Two clamps is better. Let's experiment with your drop weight if you still have the flying clamps (or you could use you new fixed clamps.) String with two clamps and when you move a clamp what happens to the weight arm? It stays level. Now do it with one clamp. When you move the clamp the weight arm drops. Which one do you think produces the most consistent tension?
If you want to straighten the strings as you go (and that's a great idea) straighten the previous string and not the one being tensioned. The one you're move the clamp from using a two clamp method.
Everyone has the right to be stupid... it's just that some people abuse the privilege
