I actually really like the 62g version. I'm happy with the 65g, but the 67g is too heavy for my tastes. I get the "Topre-like" comments, but I'm not a Topre fan anyway, so... To me it seems the 62g does have the most tactility and the smoothess makes them sooooo nice to use. With th 67g it feels like the stronger spring masks a little of the tactility. Glad I bought a few of them to test, though, otherwise it would have bugged me not knowing. They all have good "pop" thanks to the stronger Gateron contact leaf and smoothness.
A Clear slider actually has just a touch more tactility than the stock purple, but the rough surface really lets it down. If you look really closely at both together you can see the tactile bump on the Clear stem is just a touch more prominent and the purple a little less, but they're very, very similar and like I said, the smoothness trumps the bump.
In case anyone thinks I'm being overly critical of these, it's simply that they're so good that you can even notice the small details of the movement and feeling of them.
