I just got my four keyboards (one of each key switch type), and unlike a few people here I guess, I'm really happy with them! The switches are all very good. I thought it would be easy to pick my favorite, but I'm actually having a really tough time picking one to keep. I thought I would prefer the blues for sure because I've been typing on ALPS for so long, but the linear switches are not bad at all. I haven't typed much with the blacks yet, but I think they are much better than people give them credit for (or lack thereof). Definitely not too much resistance to type on...or perhaps my decades of ALPS usage have beefed up my fingers much more than the girly men who complain about them, hahaha. Construction feels really good to me, not getting this "flex" that others are talking about when pressing down the keys. I haven't had any trouble at all with the right Shift key, it's right where it should be. The backplates do look like they need to be shaved down a bit, they're slightly too big for the slot they go into, so I'm not sure how I'm going to do that.
One thing though, I thought 6KRO was supposed to be six keys plus 4 modifier keys? I can only use six total, including modifier keys. Anyway, I'm really happy with the Race, it's exactly what I've been looking for in a small keyboard. I just wish I could afford to keep them all so I could swap them out now and then. Huge props to iMav for putting this all together, can't thank you enough, man!
