I should have my full review ready soon, but I can give you my rough evaluation of the Lauf. The first hurdle to evaluating the Carbonara is relative to framing one's expectations. Calling it a "suspension fork" almost sets it up for failure. What would I call it? Dunno. But, it isn't anywhere near the same category of fork as a Bluto, Lefty, or other proper boingy front end.
If I take it for what it is, it's pretty great. I've never liked tweaking my front tire psi as a means of adjusting ride compliance and the Lauf allows me to ride with the pressure I want up front and still have a consistent amount of compliance. On hardpack trails, I tend to run a firmer tire pressure and the Lauf helps cut the edge off the bumps a bit.
At 60mm of "travel" I'm still feeling every tiny bump, but they're just less edgy and sharp. If you think about it, a rock that measures 60mm tall is not very big, so when you hit it at full-tilt-booty, you feel it. The Lauf just softens the impact a smidgen. One bump like that isn't a big deal, but 10,000 of them over the course of a ride, and the Lauf smoothness starts to pay dividends in terms of reduced fatigue.
So, in a nutshell, it's plush, smooth, compliant, but it is not really a suspension fork in the truest sense of the word.
Other upshots include the crazy low weight. It doesn't feel any heavier than the uber-light ridged carbon fork on my Beargrease. I love the zero maintenance or set up. Bolt her on and go. The build quality is also beautiful.
On the downside, and there are downsides, the Carbonara did detune the quick handling of my Beargrease a tiny bit. I have to push my turns a tad harder than before. And this is where the bigger side affect to the Lauf comes in. The lateral flex is noticeable. When climbing I feel it, but...who cares? However, when charging hard at high speed and diving into a hard turn, that flex makes holding a hard line a little tricky. Not only is the geometry more relaxed forcing more power to carve the turn, but the front end is a little vague. The guys testing these forks on snow would never notice, but on my local hardpack trails, many with beautiful high-speed sweeping turns, that flex is noticeable. Not a deal breaker, but a noticeable trade off.
So, overall, I dig it for longer rides particularly where hard-angle bumps are prevalent. I can see why the snow riders like it to soften edgy footprints in hardpack snow. I wanted it for long bikepack miles, and so far it has fit the bill.
If you're a hard charger, want maximum cornering performance and bigger-hit compliance, this isn't the fork for you. Other than that - I like it.
