Take Frontiers , drop a couple of the turds - like Back Talk - off and replace with the songs that were (stupidly) set aside for movie soundtracks at the time (Ask The Lonely, Only The Young) and that's my favourite Journey listen. I also rate Arrival reasonably high but it's a few (soft) tracks too long for my taste and it also depends which version you have - I'd definitely want To Be Alive again which isn't on one of the versions I have.
