I personally don't think a large oversized sling shot is the next step. I personally have seen stihl set his rope at least 75 feet on many occasions. and when he couldn't make the shot or had to go higher he used a tool called a rope gun that is powered by a 22 shot which is capable of shooting the rope approx 120 to 130 ft without a problem.with the rightload. If you have to go any higher than that you better get an helocopter. So don't be getting on his case when i think your the one is behind the times.
