I'm also waiting on more info on this steve but for now I think we should state that it is not the harness that may or may not need strengthening, its just the chainsaw attachment loops. I wouldn't want anyone to worry about the safety of the harness as a whole.
As I understand it new versions of the harness will have stronger attachments for chainsaws, but the origainal is not being re called. Some one else appears to know different, we'll see.
