Depends on what your wanting to do, straight stuns are more aggro then the crushes (dont use lesson stun though). But if you looking for dps + aggro use crushes.
My lineup in raids is
crush
paean
crush
elegy
glorious
provacation
and some utility stuff after those.
I never have problems with aggro, if you really want some more help, I did a nice writeup for my guild's paladins that I can PM you with a bunch of info.
I also made a informative post for my guilds paladins on dps'ing as a paladin. I am the class lead in my guild, so I had to make some posts to help some others in the guild actually do stuff lol!
