I already made 7h ride with it (4 yesterday and 3 today). When I came home yesterday I made some more kilometers with my team bike, for better comparison. Here just some photos from todays ride:

Of course I just removed the bottles only for photographing,..
Yesterday I rode with my training wheels (Mavic Aksium - Continental Ultra race tyres and Shimano Ultegra cassette: 2976g
) because most of the time I ride with them (more than 17000km of training this year only with Mavic Aksium, and a lot of races with Ritchey WCS or Ksyrium SL wheels,...and some more rides with my LW wheels, just for my soul Yesterday I made a 4h ride with a few longer climbs. First impresion is that it's very smooth and nothing special compared to my Wilier team bike. My team bike is a bit stiffer but the ride is as smooth as with my team bike. For the price of lower weight it's a bit less stiff, but still really nice to ride also for some agresive rides. In descent it's very smooth and I really enjoy the ride with it. Also the integrated saddle isn't as bad as I tought, even after 4h rides and the SLR c 64 is just perfect for me. I rode with Selle Italia SLR for the past 5 or 6 years and just after a few kilometers I get used on the c64 saddle shape. It is a bit harder (similar if you compare tubulars with clinchers) otherwise nothing special, but of course really light.
Most of my rides are in the mountains here in Slovenia (Kamniško-Savinjske Alpe etc.,..). It's just around 20km away from me and I'm almost every day there

...
I FEEL SLOVENIA, I really do
Anyway, back to the bike: in the descent I just didn't had the right feeling with KCNC brakes. For me 100g means nothing if the ride will be more reliable...and after a 85km/h descent yesterday I would rather have Sram Red brakes. I really like the Red brakes that I have on my team bike and somehow I prefer them. KCNC are not bad, but I really prefer some solid rides.. Most probably it's because my racing career, rather a few grams more and that it's solid...of course the same by me with tyres, bars, stems, etc.,... I'll most probably change the brakes and the bike will be perfect for my taste! Otherwise about the integrated saddle - already mentioned that I could still use a 34.9mm stubby or a 31.6mm seatpost, but most probably I'll let it like it is and will make a new frame for a standart seatpost later,... I could change the bottle cages and it would be still a sub 6kg bike with Sram Red brakes.
Anyway, I'm really happy with it and I'll continue riding with it as much as possible. Otherwise I have to ride with my team bike and most probably I'll ride with PROTO-TYPE 3 frame only twice a week, hopefully I'll manage to make around 2000km with it in this season and after that I'll start with some new projects and hopefully in winter there will already be a new product, will see, it depends on my free time..
My girlfriend really likes the look of this bike and maybe I'll build her a bike next year with this frame
P.S. just one more photo, a bit larger:
