In the past, I've used a flexi lead on hiking, but got a nasty lil' rope burn on my leg from a friend's flexi, so I wasn't quite as fond of them after that. I've never had one break, but Gull did chew through the line and I never replaced it.
I like to use a 30ft regular nylon lead now, for hiking or places like the beach where I want them to have a lil' more flexibility to run around. Course seems like the last few times I've gone, my friend was using my long lead for her JRT and Oz ended up on just a 6ft lead. Here's a lil' pic of Oz with his 6ft lead on and Idgie the JRT has my long 30ft red one attached:
It works really well in open spaces, which is really the only time I'd be giving them that much lead anyway. If Idg starts to toodle off from us, it's real easy to catch up and step on the leash to stop her. They do get awfully dirty, so they get tossed in the wash after any outing and they become a tangled mess if you don't coil'em up properly like you would an electrical cord.
