im going to try these for my side planers, they have a perfect grip and i got the bag for like 10 bucks. orange paint and a shower curtain clip and they should work fine. they are called clip-n-weight if ya want to get some.
Just a suggestion, I think they would work but you should cut a piece of old inter-tube into "pad" size squares and super glue them to those serrated teeth, the line could hang up on them... and a thanks for the info on an option for a cheap release...that is always good...Jimbow
