Another new guy here. (Hi all). I came to this site for the same reason as Jack. Was searching online for tips on Zone Zeus specifically.
I've got to zone 72/73 so many times it's starting to do my head in. Generally as soon as I get close I think I lose concentration and just start hitting walls all over the place. Today I got to zone 74 twice in a row, so hopefully I'll get there soon. I'm pretty sure it's just practice as I kind of plateaued at zone 68 ish for a while but kept at it and gradually improved. So yeah, I echo others' sentiments - if you really want the trophies, then stick at it. Good luck.
