Use to be compulsory when used with wire core flipline at a well known utilities company. Could never get over the stupidity of this .

Rope grab far , far better and safer imo :thumbup1:

 

 

I have used both methods but I prefare the rope prusik if I had to choose, Sometimes when you take your weight off the grab it opens and as you lean back you end up falling a bit.

 

I have a grab on my flip line but I have had to put a rope/strap piece in which can be cut in an emegency, which i think is requirement?

What's wrong with a prussik on a flip line? The one I used to use had one, no bother at all. It could be considered a safety feature: if you have a split stem and you are being crushed against the tree you might be glad to be able to cut the prussik and save yourself.

 

A soft link is a must on your steel core as said above,I use a grab with soft link,& like the fact that it can be shortened one handed,but a bit more of a pain to lengthen than a friction hitch.

The reason a prussic is not suitable is that it has equal friction in both directions, which makes one-handed tending difficult. That is why you should use a non-symmetric friction hitch such as a Distel Distel - Knots Guide | Arbtalk.co.uk or VT Valdotain - Knots Guide | Arbtalk.co.uk or even a schwabish prussik (1 + 3 turns) with a tending pulley.

 

You can use a rope grab, or an ART Positioner, but it should be connected to the carabiner using a sling (or express-sling) to provide a cut-off point.
