Personally, I did this after I had already beaten everything else. If you make sure you`ve already done everything there is to be done, there's no reason not to hit it anyhow. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> I don't remember how the stat system works, so I couldn't base my opinion on that.
Again: If you've already completed the rest 100%, why stay?
I hope this helps with your decision.
