Actually yes, razer offers one of those "Mechanical" clicky ones. My friend had them in his store, but I chose this one over it.
This one here, the "black widow"
That actually uses the same Cherry MX Blues that the Das uses, so it's actually more suited for typing than gaming.
There aren't any clicky linear ones are there?
Sadly, such a thing wouldn't be possible. The thing that gives MX Blues that satisfying click is because the actuator for the switch actually consists of two segments. The top section pushes the bottom section down, and when the switch triggers it forces the bottom segment to bottom out. When you release the key, the top segment pulls the bottom segment back up. This gives it the loud click and is what causes the separation between the actuation and release points. It also gives the keyboard an absolutely incredible feel while you're typing.
I love the idea of having nice clicky keys, but not at the expense of the keys being harder to double tap/tap quickly, etc.
It's not as bad as you might think. My StepMania game has improved despite my keyboard having MX Blues. Rubber dome switches are similar to MX Blacks in that it's very easy to double-tap when you find the right floating point. Then again, I generally jackhammer keys and don't float them, since I find that to be far more accurate.
For what you're looking for, MX Browns would probably be your best bet. It gives you the tactile bump but still has a tight actuation/release window. The only real issue is that if you release the key too much you'll get stuck on the bump on the way back down and will bottom out again. That's really the only edge that MX Blacks have on them, and MX Blacks would likely not be very pleasant to type on for extended periods of time.
