Rob, once you've had a pally judge wisdom in a fight like Magtheridon where you're essentially standing there the entire fight (minus any backup clicking duties you may have), you won't want to ever go back. In the case of Mag, JoW restores just about the same amount of mana SR does when using SR every cooldown (SR restores about 410 mana on proc untrinketed in raids).
In any event, I too have harbored the fear of losing too much Int due to wearing leather but the more my Int goes down, I can see that it truly has a very small effect. Now I just need this link handy when I bid on rogue gear.
