What Petzl do you own? Mine, the Ecrin Roc has almost no flare.

That's the one I have as well.
Was there any other helmet for the serious climber?
I still am surprised that Petzl discontinued it several years ago.Anyway, there isn't a great deal of flare, but there is some, particularly at the front. Not a big deal, just thinking I might find a cheap skateboard helmet and try it out, for grins and giggles. After all, that's why God made sidemount - for gear-heads, tinkerers and DIY'ers - right?
It is reassuring to see there are enough of us out there who (to paraphrase Clint Eastwood in Heartbreak Ridge) 'Adapt, improvise, overcome.'decompression:

Mine does not even have a manufacturer name.
Together with the hood I will probably even use it for protection.
However, here in Germany it is next to impossible to get access to a dry cave without being a real explorer with a university degree and cavediving certs are frowned upon.
So it's main use will be this:

Yes, that's one of the reasons why I went with that design of helmet. They're fairly ubiquitous and easy to source. I got mine off a local market here in the Philippines for $12.
I like the shape at the back, as the curvature doesn't impose on the neck when diving in proper trim. You can see that shape in the photo below... plenty of clearance at the back for neck mobility and it doesn't interfere with hose routing at all.

OK, your Roc is a later model than mine (you can tell by the shape of the vent holes, and the CE mark). Petzl changed the Roc design / appearance very slightly somewhere around 2000. Mine is a circa 1991 version of the Roc. But, yours still have the slight flare at the edge, a little less pronounced than the earlier design. Nice pictures, though, and I really like the mounts. And, you answered a question I was going to ask - I have an inclination to drill some vent holes in the top of mine - it traps some exhaust gas bubbles at times, affecting buoyancy. But, I see you have not. Have you given any thought to that?That's not my helmet... This is my helmet:
I use the heavy bungee as an anchoring point for the backup bungee on the lights.

I am constantly looking down in the caves, or twisting my head one side or the other. I never noticed air collecting there, much less disturbing my buoyancy. There is a hole drilled in the very back to hang it up.
FWIW, I think I bought it around 1998 or so, now that I think of it. Not certain, it could be earlier or later. Pulled the right shoulder out of the socket and the doctor told me not to climb again.
I think vent holes important because it decreases the noise of the air in the helmet.
Sounds a bit like being in a cave the whole time and can easily be ignored in overhead environments.
In open water it can be distracting, however.

Since that's where %98 of my side mount and helmet diving is done, it's no wonder I don't notice.
