All I'm looking at Seo's web site and see two very similar rope routines. Tenyo 4 Nightmare DX and Discovery Rope. (both available on the web site)
The routines look very much the same. One rope color is offered different, and the cost is about a $20 higher for one.
I have contacted Seo twice with no response, I trying to find out which is better purchase. Which has the better construction and will last with frequent use. Is the $20 extra worth it?
Any of you owning either or both I would be interested in your experiences.

Thanks.
