Hey , what racking biner would You recommend for those puppies ? I was thinking about Black Diamond OvalWire Carabiner but it has notched wire gate and its heavier than any wire gate biner for egz CAMP USA Orbit Wire which is cheaper. I wanted to take two biners to go with DMM Wallnuts - bigger sizes on one and smaller sizes on the other. Also I wanted to buy a racking biner for tricams. What do You think? Is it better to buy lighter but a bit smaller biners for racking stoppers? Or maybe with keylock? - som say that notched gate prevents of losing stoppers ;)

Mike, I'm doing something similar to how you would do it. I've got a set of 1-11 Wallnuts racked on 3 wiregate carabiners (for small, medium and large nuts). I'm not too fussed by the carabiners themselves, and have BD Neutrinos and DMM Phantoms (v light). I like the conventional shape of these carabiners for racking, and have never considered an oval. Basically an average wiregate is enough, so just get a cheap one from a decent brand that isn't excessively heavy. A non-clean nose is probably quite handy for not losing nuts, but can be quite annoying when you want to get a nut off the racking biner. I don't worry too much about losing nuts off my biner to choose between clean/non-clean noses. However, I've lost a biner of nuts, because the biner itself didn't clip on cleanly to a friend's harness (carrying lots of gear)... subtle difference there.

Although I have BD stoppers, I really like my setup of 1 Dynotron for larger nuts and 1 Nitron for smaller nuts. Both biners are large, keylock, and have bright and distinctive colors. I don't like the way ovals sit on my rack, and find that as long as you have fewer than 7 nuts on a biner, they sit nicely on D's. You do have to be somewhat careful to keep them from falling off while placing them, but this happens even with notched gates, and i think the convenience of smooth operation is worth this extra diligence. I rack Tricams all on a single orbit keylock. It is more important to have your tricam biner be keylock than your Wallnut biners, because the only thing that the webbing wants to do is get caught in the notch. Tricams are funky enough as it is.
