I have a Super X3 and I really like it. In fact I just got it patterned today. The "Dura Touch" is a feature that I like as well. It grips good in your hands but it does not allow the stock to "slide" across your face as a wooden stock would. The SX3 should come with a set of shims that will help you get a better fit but there is nothing like having a professional get you set up correctly if the problem is that bad. I'd work on the price just a little too!!!
Good luck!
