I've recently begun jump roping as I enjoy it and am working on bringing up my conditioning. I'm 6'4 and, from the research I've done, I think I need a bigger jump rope. I've searched and they say people over 6ft need a 10ft rope. I have a crappy nylon one now that the PE teacher at the school I work at gave me, but it's very tangled and is hard to use and get into a rhythm with. I've thought about just a regular old rope but I thought that may be too heavy to turn with any speed and it might be too thick. I've looked at sporting goods stores, etc., with no luck. Any help would be appreciated. Thanks, guys.
