Zipline Help — Bungee Brake

Here is a question I received from Jason Devine in Kentucky, USA

"Hello, I'm currently using a bungee brake on our commercial zip line, but as we are trying to accommodate a wide range of weight (70-250 lb), it is somewhat difficult to manage. While our speeds are only around 25-30mph, we are trying to stop on a platform and it can be difficult. I'm wondering if the Counterweight Progressive Brake would be an option for us? We need to keep it economical so the zip stop is out of our range. I appreciate any help you can provide....
