I have used a ton of slings over the years, but I ended up making my own. It is adjustable, but not real quick. I don’t have pull tabs or anything like that. I don’t care for excessive webbing and material that can get caught up on shit. I used two pieces of 1” tubular nylon. The main piece has loop on each end and the second piece is shorter and has slots sewn into it and it is sewn onto the main piece. I run the loops through a QD attachment and then use small S caribiners to attach the loops to the smaller sections to make the sling sized to whatever I need. That is probably a horrible description, I can snap a few pics if anyone is interested.
