Huh. Nice vid. I have had my eye on the crossropes for a while but seem a bit pricy for where I am currently at. Once I am a proven jump roper I will prolly invest in them.
As for length, I bought a 10 footer from my boxing gym and it seems okay, but I still trip up sometimes. Also, the rope I bought from Amazon (this one) is supposedly 10' as well.
I am now thinking I might just be doing something wrong.
