Slack Science, powered by Balance Community: Slackline Outfitters, is a blog run by Jerry Miszewski about slacklining. He offers tips and tricks to various parts of setting-up, taking down, in-depth looks at various aspects of a setup, and hints at walking slacklines.
Jerry's long history with the sport of slackline has given him a wealth of knowledge that he loves to share with his fellow slackliners. Slack Science is a place anyone and everyone to come and learn about our wonderful sport of slacklining.

We've spent the past couple of days learning about the various parts of our pulley system and the components that make up these parts. Here's the comprehensive guide to building your pulley system and choosing the right components for the types of lines you are rigging.
Part 1: Main Pulley Characteristics
The powerhouse of your pulley system: the Main Pulleys. There are various characteristics to look out for when purchasing a set of pulleys for your main pulleys in your slackline tensioning system. All of these characteristics play an important role in how efficient your over system is. Take a gander at this post to learn more.
Part 2: Brake Characteristics
The part of your pulley system that holds all the tension: the brake. Not only does the brake progressively capture the tension you pull out of your slackline, but it's also where you will be releasing tension from your line. An extremely important aspect of your slackline pulley system.
Part 3: Connection Point Characteristics
An analysis of the various ways of connecting your pulley system to your anchor. We take a look at 3 different ways of anchoring and the pros and cons of each. We also delve into the types of rigging plates offerend at Balance Community and how they compare to each other.
Part 4: Rope Characteristics
A very important part of your slackline pulley system: the rope. Often overlooked, the type of rope you use can have a big impact on the ease of tensioning as well as the mechanical advantage of your pulley system. We take an in-depth look at the various characteristics to look out for in your pulley system rope.
Part 5: Multiplier Characteristics
The most underrated part of the pulley system: the multiplier. This is the part of the pulley system that has the fastest traveling rope and adds the most power to your system. There are a few components to this component of your pulley system. We take a look at each and offer a few different options while going into depth for each.

Hey Austin,
Thanks for the comment and the interest in progressing in the sport. I've never actually used the Rock Exotica Omni pulleys, but I can tell you that from the specs of the pulley, you will start to run into problems in the 250-300 ft. range. The smaller sheave size of the Omni Block will greatly reduce your mechanical advantage when trying to setup a line that is in the 400-500 ft. range. I would seriously consider getting a 4-pack of the SMC 3" double PMP's if you want the most bang for your buck. I have this pulley system and have been using it for the past 4 years and I can setup 1600 ft. slacklines with it...no problem. That's not even the limit either!
Shoot me an email at Info@balancecommunity.com and I can hook you up with a deal for the 4-pack.

After slacking for about a year now, my buddies and I have decided to take up long lining/high lining. I am the climber in the crowd and naturally have a majority of the gear necessary to set up a 5.1 system. However, I do not have the pulleys that will be necessary for the set up. I have been engulfed in the balance community forums for the last couple months trying to learn as much as possible before I buy my gear. My main question is this, would the Rock Exotica Omni 1.5 double pulley work for a 4-500 ft long line?
