In reply to John1458:
We didn't have Blue Ice there per se. more lots of gear as prizes from the local shop. No steel version has arrived here yet unfortunately. My observations above stem from playing around with friends/ the locals screws as most people have already purchased them. We did however have CAMP as a sponsor and their screws are actually worth a look.
If you were with the guys from the Gwent then I have seen some pics of your revolutions in action. Gave me nightmarish flashbacks to mine I used years ago, so can entirely understand your desire to upgrade. Tho I will say they are a very nice screw!
For a recommendation I would argue that the Petzl screws are probably still the best way to go, yes they have their issues but in 5 seasons of use I've never really had that much of a problem and would say they are certainly the more reliable aluminium screw out there. The floppy handle issue can easily be fixed with a hammer and a punch. I can't comment on the newer three tooth design and whether there are any benefits tho. In the future I will likely buy Petzl again but with a mix of alu and steel.
Whilst light is a nice concept, an entire rack of BD steel screws never really slowed me down so I'd rather save weight elsewhere on my rack than invest in protective gear that has a risk of breakage in use. I will admit however to having taken a casual interest in the Kailas Swift which have actually received very good feedback. They have had rare issues (similar to the petzl tube cracking) that is apparently being remedied, so if you're feeling exotic they may be worth keeping an eye out for if they re-release them.
