Hmmm, when you look at it all cams must meet certain safety standards otherwise they wouldn’t sell, right? So if all the above manufacturers are above the safety requirements, then choice comes down to weight, survivability, ease of use and personal preference, right? And price of course. Weight is really only a problem on multipitch isn’t it? 40m climbs aren’t going to require enough gear to quibble over a few grams. By the sounds of it any cam will last as long as, you take care and service them, naturally. Ease of use is sought of connected to personal preference.
So it sought of comes down to price and whether or not you want the extra bells and whistles and the BIG name to go with it.
Agreed?
