Qwik Slate is the system from Newmont; it actually has a 3" or 4" headlap. Newmont makes another product called Slate Shield that relies on HDPE in between the courses. (High Density Proplyethelene). It relies totally on underlayment.
We've installed hundreds of squares of the Qwik slate system. It has head lap, and it's a tried and true method (stainless steel hooks) used in Europe for over a century.
Some people don't like it because the hooks can be seen to a degree, but depending on the height, pitch, and color of the slate, it can vary from very obvious to barely perceptible. One church we used it on is a 7/12 2-3 story roof and dark Spanish Del Carmen slate, and it's not noticeable at all.

Lifer, When is a slate roof not a slate roof? If you are talking about the system where the hooks are installed and partial slates are used with a 3" head lap, you have to know that it is slate on the top, but the roof is really the underlayment beneath. It is lighter, it may be faster, but it is not a slate roof per-se. Also, you don't know where the slate they are using is coming from. If it comes from Brazil, most of that will be trash on the roof in a couple of years.
There is a system of hooking that is made here in the U. S. that uses real full sized slates and it is a perfectly good option. A lot of the slates installed in Europe are hooked instead of nailed, and you really don't see the hooks all that much. The real question is not about the hooks, but how good it is and how long it will last. You have some more researching to do before you pull that trigger. Good luck

I have a 25 SQ. Church to do with Mottled purple and green slate and was thinking about using the qwik slate system to install it. Anyone got any thoughts on the look of the exposed hooks? The roof is not that high off the ground, maybe 15 - 20 feet to the gutter line and it is wide open with nothing to break it up or distract the eye. Anybody used this system and how visible are these hooks really?
