Speedfi speeds it up
"Still a newbie aid climber, but this product makes the whole process a lot smoother and more efficient than my regular fifi. To be honest, I got this initially instead of others because of the price. But now I'm finding that there are few features that I prefer. A few things that I noticed that are different/same from the other adjustable fifis that my partners are using: 1) I can use this with either hand and not twist webbing since there is no webbing. 2) Uses rope instead of webbing so it's a bit more dynamic although you still are not supposed to fall on it. 3) With practice, there's about the same amount of friction/resistance as using the webbing-based one. 4) Looks like it would be fairly easy to replace the rope on the Speedfi if necessary."
