Alright, I've added some action shots and I'll provide my review here.
You can find a spreadsheet of my build at this link:

When I first built it up, it weighed about 16.6lb (incl. pedals & cages). I have since gotten that down to 16.2lb by swapping out some parts and cutting down the seatpost. Check the spreadsheet for detailed weights.
Re: seatpost slipping, I have experienced problems with that myself, as well as creaking. I have gone into more detail on weight weenies, but basically the seat post as a lot of slop between the seat tube, and it makes it so the compressor has to do pretty much all stabilization. This is not an uncommon problem, and while most manufacturers put in a chunky compressor to solve this problem, Seka's is small and flimsy for weight saving. Furthermore, Seka's stock seatpost is VERY long, so at even normal post heights, you will hit the seat tube cutout changing the post angle, and this messes up the interface with the compressor. So you NEED to cut the post, both to avoid damaging your frame, and to ensure a proper interface. I have addressed this issue with lots of carbon paste, putting 3M protective film on the surface that doesn't touch the plug to take up that slack, and overtorqueing the screw a bit, and since dialing this in, I haven't experienced problems with slipping.
Re: Flex, my previous bike was a Tarmac SL5, bikes in general have gotten much stiffer since then. This bike feels stiffer yet more vertically compliant compared to my Tarmac. When I first got the bike, I sensed a lot of fork flex under braking. Since then I've tightened up the headset and haven't noticed it. Either I've gotten used to it or it was the headset. I do not experience fork chatter under braking like you do with some really flexy front ends.
Re: Price, preorder was $581USD, remaining was $1290USD. This is the final price billed to my card, which includes shipping/customs fees.
Re: Elves falath evo or Seka, I would choose Seka. Take this all with a grain of salt since the Seka--being a semi-aero bike--has a different design philosophy/goals to the Evo, and I've never even seen an Elves in real life. But, based on all the build videos I've been watching from the usual youtubers, I really do not like the Falath Evo. I don't think it fulfills the goal of being an aero bike very well. If you really look at the tubes, lot of the design doesn't make sense aerodynamically:
The leading edge of the downtube is a semi-square face, when you want a rounded one. Same goes for the seat tube gusset. All leading edges on the Seka are rounded.
There's huge gaps between the seat tube cutout and the tire, even when running a 32mm tire. The Seka also has gaps, but they're smaller, not to mention that Seka isn't intending to shroud the wheels as much as the Evo is.
The Evo's headtube--the most aerodynamically sensitive area on the bike, is the widest I've ever seen, which runs counter to how western brands like Cannondale are doing everything possible to make the headtube as narrow as possible to minimize the frontal cross section. Seka's is much narrower, and even has an hourglass profile to minimize it even more.
I don't think the way the Evo's integration of the headtube with the top tube improves aerodynamics. TT bikes do it because the base bar is always designed to run slammed with the stem flush to the top tube. I think the way the Evo executes it actually presents more frontal area compared to a conventional, lower top tube.
The Evo's super-narrow downtube does next to nothing to shield the water bottle. I'm of the opinion that every aero bike should be designed with round standard bottles in mind. The reality is that sane people not racing a TT will ride with round water bottles, and the water bottle will spoil all the airflow coming off that narrow down tube on the Evo. In contrast, the Seka's downtube gently flares out as it approaches the bottle to shield it a bit more. The shielding isn't perfect (as on most bikes), but at least it's considered on the Seka.
All in all, I would not be surprised if someone put the Seka and Evo in a windtunnel (with 2 water bottles on each bike), that it turns out the Evo is not actually faster than the Seka.
Lastly, I think the fact that Seka is willing to show off their carbon under clearcoat while Elves paints over EVERYTHING says that either Seka's paint and finishing is just a tad better, or that Elves may even be trying to hide imperfections in layup. Seka's paint isn't exactly phenomenal (soft, scratches easily, comes with subtle scratches/swirls in the clearcoat), but it's very special to see the carbon underneath.
Coulmain made the point that for average riders, "aero optimization" doesn't really matter. My counter to that is that a) all of these un-optimized features add up, and b) if it doesn't really matter, then don't bother with an aero bike, or at least not one that postures as a super-aero bike. You pay for "aero features" in weight, comfort, impact resistance, and added engineering/manufacturing complexity that trickles down to cost. I think Coulmain weighed in a 52cm at over 1200 grams. If that's a 52, what could a 56 be? 1300g?!! Meanwhile a 52cm Seka Exceed Std is about 950 grams I think. That means the Evo is ~20% heavier! I have a hard time believing the Evo's aero gains--if there are any, are enough to offset that much of a weight penalty.
