I used grab hooks with the pin for attaching a chain. Welded them on while leaving the holes for the pin. Then, got a short length of light wire chain and attached it by using the pin. Now, with benefit of a double snap catch, I can attach 5 gallon buckets on either side of the bucket and/or front via the center grab hook.
When fencing, I place T posts in the FEL bucket. Pull old wooden posts with the FEL and place them in FEL bucket, drive the T post with bottom of FEL with a pipe sheath covering so T post doesn't bend. Tools and supplies are distributed in the 5 gallon buckets. Trash such as busted electric insulators, pieces of wire, etc. goes into a 5 gallon bucket.
This lets me and a buddy work a fence line easily. He drives up to the fence and performs FEL operations at my direction while I perform whatever needs to be done.. pulling crooked/busted posts using chain in grab hook, driving new ones in, repairing/removing/installing electric insulators and t post clips.
Net, I PREFER the regular grab hooks and use the extra attachment points they provide to my benefit.
