Yes - but then we solely rely on a mechanical release as the ONLY release option, just like the release schackles (we abandoned because) - with no options to get yourself "clear" if it jams
As said, it is maybe just me - but like the idea of being able to get yourself "unstuck" if something else fails
i suppose if you are really worried about your QR failing i would check into two things
1) a better QR you can trust more
2) a quick-release pin on one end of the rope to release the whole mess
Well, I trust my release a lot, as it is the "French" type that can not be jammed because of sand or dirt or rust or anything - so not possible to find one that can be trusted more
But I were speaking generally, why I dont like to be "locked" to my equipment via one single way of disconnecting myself.
As there are no downsides with the hook IMO, I still prefer to have extra options to free yourself - like taking the CL out of the hook f.ex.
Regarding getting stuck in the hook - I checked mine today, and the hook is actually so big and a very open hook, so the bar can get into the arc yes, but very very easy drops out again
Are some hooks so small that the bar can get caught and not easy to free ?
Maybe the problem is those hooks just about the same size as the bar diameter, where it might get stuck ?
