I have been using ovals for my bridge attachment, but I'm think to use a Pirate or other HMS type to get more room for a stack-up including:
1) Pinto with rope wrench tether inside, 2) two knot-tied friction hitch ends.
My question is:
After installing an oval, can rotate so that it opens down and accepts the bridge fitting (a small rigging plate), but with HMS style it seems they only open up.
How does one clip the bridge device in?
Does the Pirate support a Pinto?
This is why the tether I designed came about. It originally was made just to straddle the Hitch Climber Pulley, but I soon realized that being able to rotate the carabiner 180 was really advantageous when using bridge attachments with smaller openings, such as the DMM Axis Swivel.
If your bridge has a ring on it, or a Petzl Swivel (S or L), or a Rock Exotica Orbitor, you'll have enough room to pass the carabiner gate through the attachment point. The only hassle with that is having enough room along the top edge of the carabiner to hold all that's stacked onto it AND the bridge attachment, and still be able to open the gate. I got over that nonsense quickly and set up the tether to work with the Rope Wrench, HC Pulley, stitched or knotted 8mm hitch cord, and a single oval biner.
Not everybody climbs with a swivel on their bridge, but I really find it to be advantageous in many situations. Say you lead out to a station with the left side of your body forward but need to switch to right part way there and you want to swing your tail over to keep it fair-leaded behind you... stuff like that.
So I like a swivel, and I want enough room in the swivel eye for 2 carabiners, and they both have to be inverted ovals so either one can go in or out at any time, no passing the gate to muck with.
Either get a larger bridge attachment point, or stick with the oval carabiner, in my opinion.
