Have you picked up a few tricks since then?....
Of course, for this session, for the first time ever, all three of the fighters showed up. It was a last minute thing and some of them arrived as the session was underway, so I didn't have the time (or then, the skill) to change things. When they caught him, they took out the big bad in the first round and his bodyguards the second.

I have a couple in my regular campaign due to very varying number of players:
- Adjust the HP of monsters +50% -50% and so on
- Adjust the attack of the monsters +50% damage, -50% damage
- Adjust the to-hit/defense of monsters by +/- 2
For 4e I just use a template for my monsters: +100% hp +100% attacks OR damage, one free recharge or a power. I add this template to one monster for every player more than 5. For smaller parties, I remove one monster per character less than 5.
