I am the proud owner of an LT and a ZX. If you're looking for user impressions, I will advise you to go with the ZX, especially if you have any guitar experience. It just "feels" right on a strap... it ergonomically fits like a guitar, and the pads are plenty close. I agree with the prior statement that the LT might be preferable for seated playing; I use mine on a stand exclusively... in fact, mine doesn't even HAVE straplocks on it.
By the way, speaking of the stand, I'll have to get pics up of mine. I modified the Zendrum Co. wooden stand plate on my tablesaw and router table (I removed the "wing" portions and shortened the front "nose" so it matches the contour of the front of the LT) and screwed a Roland-style module bracket to the bottom (a metal one, not Roland's plastic model) and mounted THAT into the middle tube of a Tama cymbal stand. It is tall enough for standing play (that's what I use it for) and looks way cleaner than having it clamped in a snare stand basket.
