I have been using an Ergo since it came out. I like the rigid leg pads. Nice cross of allowing leg movement, but not cutting into my legs.
I keep two DMM Vaults on either side for equipment. The right side holds a chainsaw and a saw lanyard.
I also use the suspension straps with the croll. One of the main reasons is that I use the harness for both work positioning and fall arrest. Just easier for me to travel with one harness. I have found some creative uses for the croll in conjunction with a positioning hook.
The only downside is as it is fall arrest rated, it is heavy compared to other harnesses. I don't mind most of the time as it is fitted well. I like longer positioning lanyards, so any harness I use would be heavier than most.
