Guys,
Thanks for all the replies.
I think I could live with the soft boltheads. I never torque the stems to the max because there is no need to. I have seen a critical fork failure (Scott CR1 + Ritchey WCS stem) due to tightening the stems to the max or above.
Maybe the frontplate bolts need to be tightened a little bit more because if you hit a hole at high speed unprepared the bar can slip and rotate forward.
I usually put some carbon anti seize grease between the bar and the stem, that increases the friction and lowers the required torque.

Anyway, I am also considering 3T ARX Team alloy stem. Currently Im using Ritchey 4axis WCS and its extremely soft at 130mm.
PRO stems are good but they are all 10deg, I need 6.

@Ritchey: Do you now ship the stems with the hex bolts instead? Is the C260 significally stiffer than 4axis at 130mm?

Another question: I have a FSA K-force compact bar. Is there any known problem with the instalation since the bar is a little profiled on the top?

First, that is the WCS C260 BB aluminum.

Second, I have the same stem in the photo you posted, mne says 5nm. Maybe they have different production runs and adjusted the nm required after some study to 5nm.

@borja

The slip like you describe happened to me last week a day or so after posting here. I figured it was karma.

:)
Put some carbon instalation paste between the stem and the bar and tighten. It should be ok.
I use this from FSA..
