Humanx makes good stuff. I haven't used their speed ropes. I prefer ropes that have bearings in both the handle and where the rope spins in the handles.
Give it a go and find out. Looks like you already bought it.
I got an rpm rope a few months back. I can rip out a lot bigger sets now. That one looks very similar to the sr3 I was using for a while. It's a good smooth rope too
