In reply to chembhoy:
> whats your view on the topic of screwgates
I tend to agree with Mark Stevenson's post above. I've cut down to six, from double that, by leaving behind the ones I used to carry on slings. The six left are: HMS for belay device (DMM Boa), second HMS for connection to belay (DMM Boa), two lightweight HMS (DMM Sentinel) for use on belay anchors and two lightweight d-shaped (Edelrid Golden Gate) for ab safety/self-rescue and therefore seldom used.
> and why they are usually mentioned w.r.t. belays only and not on runners...
1) Speed and ease of use - even if you don't do up a screwgate, clipping in is not quite as convenient because the rope/your finger can't slide along the nice smooth gate and that can make a difference if you're starting to pump out/fall off.
2) With a runner, you will normally expect another one further up the pitch so it only needs to be "good enough". The belay just
has to hold - possibly a factor 2 fall, or close to it if the leader's runners all turn out to be cack. (But even so there's an argument that a screwgate is OTT for everything except the connection to the "power point" - and maybe even there.)
3) Weight and cost.
Some may argue that a screwgate should be used on a runner if there is a risk of the krab's gate being obstructed by the rock in a fall. I don't believe that screwgate sleeves are very strong in themselves* so there would still seem to be a risk of damage and possible failure in such a circumstance. I'd prefer to re-organise the gear and the connection to it to avoid the problem, if at all possible.
* There's no test for sleeve strength in the UIAA spec and in krabs available as both snapgate and screwgate eg the DMM TruScrew/Truclip, the cross-loaded strength is the same so the sleeve doesn't seem to add anything.
