^ Yeah I saw that. The slots make it somewhat lighter, which is nice hauling gear around, and relieves things when hoisted high up on a stand. I suppose you might be extending it fully out and then positioning the mics along the slots to fine tune spacing width, but I can't see how the lack of slots should limit the effective spacing range able to be achieved with the newer design. You'd just need to make is zig to some degree instead of keeping it fully straight to achieve a spacings narrower than the full 55cm. With the arms folded in all the way, the minimum width using the outer mounting positions should be just over 18cm / 7", then if switching to the holes mid-way out it should range from right around 18cm/ 7" again all the way down to just a couple inches, should accommodate coincident X/Y configurations with the pair crossed.
