BP - I know what Im saying mate, the tri-lock that I am particularly talking about is the Kong http://www.rockhardware.com.au/Order.asp?Action=View&StockCode=KG9120004&MainGroup=Karabiners
You can replicate the action with your hand, picture holding the biner, gate facing you. Then strike the gate with a glancing downwards blow using the knife edge of your hand and it will open. Granted they wont do the reverse-vibrate open thingy that you have experienced but the action that will open it with your hand is not something that would be unlikely on the rock. Not impossible by a long stretch........

Im pretty sure the Kong biners are aimed at rope access types - as you mentioned - using gloves (less dexterity) and less likely to be slapped around rocks constantly - more likely to be used close to the harness or through purpose placed ring bolt anchors but I personally have played with them enough to favour other triple action biners in either situation - or maillon rapides.

In the case of Petzl Williams etc. (with the ball) I cant see anything happening that would open the gate and as mentioned they can be a pain in the arse to open intentionally!!

As for the rope drag point, I meant - what was mentioned in a later post - that it creates a greater radius and reduces the wear/angle that the rope passes through the culmination point (next best thing being a pulley) effectively reducing rope "drag" for the belay person.

I dont commit myself to such comments that easily, and wouldnt of had I not played around with the items myself.
