I got to thinking about the recommendation by Antsy [ANSI] to only use cinching knots so as to prevent escape of the knot from the carabiner and to prevent improper loading. While the recommendation is a good idea, and it reduces the probability of those errors, I don't see it as a necessary requirement. Here is why:
Spliced eyes are generally considered superior attachments to a carabiner than any knot, and they do not cinch down at all. Therefore, the cinching requirement cannot be considered a primary concern in the safety of any knot that serves the same purpose as a spliced eye.
Since many of the various knots available are equally reliable, there is no reason not to learn a good cinching knot. On the other hand, if you happen to be "knot-disabled", and learning to do a triple fisherman is a challenge for you, then you had better stick to what you know is safe. If you only know a bowline, and you do it right every time, then perhaps you should stick with that.
My personal opinion is that "knot-disabled" persons should learn a less dangerous trade.
