You cannot use the BD wire gate oval that comes with their nut set to hold your nuts. You need a solid gate oval. I was told this by my climbing mentor once before I led a climb (with my new nuts and accompanying wire gate biner). I thought “ok, sure, I'll think about it” . During the climb I experienced the reason why a wire gate is not a good idea here. When testing the nut, giving it a good tug with the biner/rest of the nuts, the placed nut somehow came off the wire gate biner. What?! That week I purchased a solid gate oval and have never had this issue again. I wish BD would sell their nuts with the solid gate instead.
Occasionally I use this wire gate for my glacier travels for my rescue system instead (with pully/prussik/knife). But my Omega Pacific oval is a bit smaller/lighter and does the job just as well (it has a smaller gate opening, but with such infrequent use it's not an issue at all).
