Good question. There seems to be 2 schools of thought on this. I used to like gates opposite to the direction of climbing which typically keeps the gate from being opened against featured protruding rock. These days I like gates towards the direction because most of the time the gate is not opened on flat or overhanging rock. I feel more comfortable this way because the rope during a fall would slide along the spine and not the gate. Since the gate is the weakest part of the carabineer and the spine the strongest. More of a personal preference. Sometimes on featured rock, I will switch it up if the carabineer lays awkwardly or is opened. It's always a good idea to watch your pro after to pass it to make sure everything is laying correctly before it's too late to fix it. Anyway, I've seen it illustrated in official climbing manuals both ways being correct. Thanks for the question and watching🤙
