Tip: Take a look at the skill tricks from Complete Scoundrel. There are a few of them that I absolutely love. If you've got a lot of skill points, pay 2 points for each of these abilities and you can:

Twisted Charge:
Prerequisite: Balance 5 ranks, Tumble 5 ranks
Make one direction change during a charge

Nimble Charge:
Prerequisite: Balance 5 ranks
Run or charge across difficult surface without Balance check

Extreme Leap:
Prerequisite: Jump 5 ranks
Horizontal jump of at least 10 feet allows 10 extra feet of movement that round

I really love the last one. Shock Trooper + Leap Attack, and then use this and take a five-foot step to prevent a full attack from enemies, and then charge again? Awesome.
