Who said anything about replacing the crane ball?
The manufacturer's hook sucks for this industry, not the ball itself.
All it takes to get into trouble is the rigging being on one side of a big lateral branch, and the ball n hook on the other side for goodness sakes!
Have you got X ray vision that sees through thick conifer's or somethin?
We have enough accidents in this biz as it is mate.
Spring loaded latch gates, even those that lock and are pinned closed, fail all too often when bent the other way. I've seen it happen many times. The Shur Loc hook by Crosby eliminates the possibility of that happening.
I gather you're such a good CO that your ball hook n rigging never swings about eh?
Gamble with your own well being mate, and quit with the bogus advice to CO's in this biz already, seriously.
Being a CO may be demanding no doubt, but very few die at work compared to treeworkers on the job.

It was hard enough to make ridin the hook legal in this biz, and you n your spring latch hooks are a great way to ruin that progress for all of us.
