Mike, you missed my point, which is that, sometimes simple is better.
If I'm trying to hit a 70 ft high target, then sure get out the throw line. Most times you don't need to set a line that high to pull over a tree.
By using a new fangled rope, LJ has taken out the step of messing with the throw line. Black Widow is plenty strong and light enough that with just a little added weight, it becomes a throw line.
The idea of using a carabiner instead of a bag is not something I would do every day, but if it saved me a trip to the truck to quickly set a line, I'd do it, carefully.
If you think the rope is too expensive, well, I'd hate to see what other tools you don't have to "save" money.
The kid had a good idea, give him credit.
And Mike, groundmen are not for spending all their time chasing after me cleaning up unnecassary steps I've taken, they are part of the team to complete a job.
