Not used that pad so I can't really say but coming from an old Ice Mat glass pad to a cloth pad it does take some getting used to but I much prefer the control of the Hien plus I am not dusting it off every 10 minutes. A decent cloth pad will still remain a smooth glide so you should have no worries in that regard.
The mouse wheel on mine feels still feels stable even when scrolling up, its just the awkward noise I hear. Its not as bad as the Steelseries Xai I tried a while back, I found the scroll on that mouse to be terrible, something I could not live with.
Both buttons on my mouse feel OK as well, no abnormally loud click either - i'll double check when I get back tonight, it may exist but not enough to annoy me. I do however normally get annoyed by things like this.
I like the quality of the mouse, though I think the coating may have a tendency to go shiney (not wear) quickly around where your fingers rest on the top buttons.
