Mobile Fall Arrester
The components of the ASAP mobile fall arrester system (shown below) are what you will need to utilize 11 mm ropes.
This system functions similarly to a seat belt, and will allow a user to go down (using both hands for carrying gear or holding onto the ladder.
If you accelerate downwards too quickly it grabs the rope.
There are a couple products in the marketplace that perform a similar function, however in my opinion, they are not as good or worth the risk. One of the best features of the ASAP system I believe is that if you are sliding down a metal roof and instinctively grab at the device, it still functions the exact same and will catch on the rope once it is moving quickly enough. Some devices on the market (when grabbed) may send the user into a free fall.
We use this system daily, and have done so for years. It has saved one of our employees when he fell off the ladder as he was pulling some slate ... safely and practically instantly catching him and holding him suspended until he could get back onto the ladder. Remember, OSHA does not require "fall protection" on ladders. They require "3 points of contact", but it's impossible to work off a ladder while holding onto the ladder at the same time. So, we always just use fall protection (which eliminates the 3 point of contact requirement).
This system is expensive. You are worth it. I've used mine for over 5 years and have replaced the lanyard.

Things to notice from this photo:
1. The rope is tight, and remains in front our our team member.
2. We utilize "stop knots" and tie them above the eve of the roof so that we can avoid suspensions over the eve.
3. We always utilize head (vented helmet with a chin strap) and eye protection.
4. Use of the pre-sternal ring on the harness allows the worker to wear a coat over the harness rather than try and wear a harness with a doral ring over his Winter coat. This is also useful because when the sun hits the roof, he will be taking off his coat and never have it change his fall protection system.
