I've got a Buddy Artic ablj, a buddy bcd and a wing. I like my ABLJ it originally came without a power inflator and had a small air cylinder, (known locally as a suicide bottle). With a row of press studs on the sides to hold a fold, this ABLJ is streamlined, lightweight and versitile. There's a small problem using one with a standard dry suit as the Ablj covers a chest centre positioned suit inflator. Compared to my buddy BCD jacket there's a lot less drag. With a wetsuit, ballast trim alterations are needed as the buoyancy compensation bubble is concentrated closer to the head.
