Got a full sized Code with clears in the mail today. Have only used it at work for a couple hours. It's growing on me.
At first I was put off by the heavy feel to the clears, I'm used to browns. After a while though I start to see the light. Real nice tactile bump and plenty of spring to keep you from bottoming out. In general I make less errors with this but I'm slightly slower.
Mine doesn't ping much, maybe a little more than any of my other V2 keyboards, but if I'm not listing for it I never notice it.
3. When I was installing my Vortex key cap set, I noticed that they didn't lube the stabilizers on all the keys that had them (except for the spacebar). So I relubed them, and they're all fine and dandy now, but they were before I did this too. Just so you know, it might be a problem later if you don't lube them. Squeaky keys and such... Anyways, I found it really hard to put the keys back on because the stabilizers wouldn't rotate all the way out. Don't know why because my other WASD did. This made it rather difficult to gauge if they were on or not. Also, after installing the spacebar, I noticed that it now clicked like a Cherry MX Blue. LOL. WAT? I took it off and relubed it, but the click still persisted. I assume it's just the new spacebar's minutely larger size/thickness/weight that is doing something weird under there. Doesn't bother me because it still functions just fine.
I noticed the same thing with the Code. Lube on only the space bar vs the V2 where there was lube on everything. I assume the stabilizers don't rotate like the V2 because the switches are wrong way round for the led's.
I also encountered the same thing that you did with the clicking except it happened with the 0 key on the number pad. It was the stabilizer because without it the noise went away. I messed around for a while trying to fix it. What worked was taking a little bit of the bend out of the stabilizer where it crosses next to the switch. Not sure why that worked for me but it did.
