I really don't like to start with Perfect Balance. It just makes it harder on the tank to establish agro and you're only losing out on like 15 secs of not being in greased lightning 3. I like to use it when we need to burn in a boss phase, and stack up buffs and basically apply DK/twin snakes in the rotation right before (still in GL3), and then have a full PB of just buffed Snap Punches (which crit for like 650-680 for me currently), and maybe a buffed Demolish as PB fades off. Seems like this way is better in my opinion, aside from PB taking longer to cool down so you can't use it twice in a fight sometimes unless it's a real long fight.
