I think hooking to the strut has only advantages and no disadvantages. The problem that I had is that I couldn't seem to get it mocked up in a way that would allow full suspension travel without the sway bar hitting the tie rod. If I were to do this project again I would now have different tie rods which aren't bent and would allow a little more clearance, and I'm also planning on running a stiffer spring rate so I probably wouldn't worry as much about binding and would instead just limit the suspension travel.
I haven't read the article, just got my first issue of RCE this week. I have heard of the angle of the end link changing the amount of force on the control arm before, which is why I tried to set them up level at ride height, and also why I mounted the lower part of the rear end links under the control arm. That allowed me to lengthen the rear links by about 2".
