Thanks!
Right now i'm leaning towards the black tape, since the white kind of crashes with the pale tanwalls.
It's not really apparent on photos, but in real life there was just something about the different hues that didn't harmonize.
it worked a lot better before, with the old blue rubino pro tires, but i think corsas ride a lot better, so thats what i'm gonna use.
as for the handlebar and stem i'm still undecided, as i need to try them out for a bit, to see if i find them comfortable, and right now there is too much snow.
i do love the look of the deda murex stem though, so i might go back to that one either way.
as for how the different bikes feel, due to the winter still holding on, i haven't really gotten to ride any of them properly yet.
i did get a quick ride around the neighborhood the other day due to the snow clearing away for a day, and the 600 and 7800 equipped bikes do feel surprisingly different - due to the stiff modern deepish wheels and stiffer cranks, the 7800 equipped bike felt a lot faster and stiffer. deep wheels just feels like they are pulling you along when you get up to speed, and that in turn make the bike feel a lot more modern compared to the tubular equipped 600 bike.
as for the caad 12, it handles like its on rails, and is super stiff and responsive when hammering it, so it's gonna be a tough contender for the steel bikes to match.
the SLX frames feel very springy compared to the alu frame, almost like a taut muscle that bounces about when you push it.
it's a lot of fun to ride, but i suspect it's not as efficient, since it doesn't have that instant acceleration or feedback that you get from the CAAD.
spring is just around the corner though, so once the snow clears and the temperature comes above freezing, i'm gonna give them all a good thrashing, and really figure out how they behave compared to each other.
