I think you're right about the Julius and, IMHO, the double clips, front and back, are a must especially with big dogs or, as you said ff, there'd be skiing

.
I definitely won't use a collar on my Pap, I don't even like one on my JRT X day poodle - I bought him a beautiful leather lurcher collar and lead, but I don't even like using that. I've even got a tiny Mekuti harness for Pap.
I still had my Elkhound when I first got these harnesses and she was a 'on the way out, excited puller'. It made a massive difference straight away, like you, she seemed to know the front cross lead meant business.
I use the back clip like Jodie (?) says, with a long line or even just the full length of a double ended lead to giving a bit of freedom and sniff time.
