I found it very clunky, too much movement, not tight. Short throw yes but far too much play in it even within that short throw. Clutch is really heavy and doesn't mate up well to a short throw if you ask me. Synchro's go far too early on a Zed for my liking also, lots of threads on here covering that.
Super engine, a good noise once you change the exhaust, but that transmission, its a shocker. Having got my go kart VX after the Zed, have to say the gear change in that made it feel like I was changing gear in a lorry in the Zed.
