Optimizing Chain Fighter class 3.5

[XReaverX3]

Hi, I have not really seen a full built chain fighter nor in game or on paper so I was hoping to get some help in how it looks. the reqs are lvl 7 lawful evil fighter 19,000 gold to spend on any items no cap on money spent per item. also its a 32 pt buy.

[Eldariel]

Have:
Power Attack
EWP: Spiked Chain
Combat Expertise
Combat Reflexes
Improved Trip
Stand Still (http://www.d20srd.org/srd/psionic/psionicFeats.htm#standStill) (backup for enemies too large to trip)
Deft Opportunist [Complete Adventurer]
Mage Slayer [Complete Arcane]
Hold the Line [Complete Warrior]
Martial Stance: Thicket of Blades [Tome of Battle] (for a Fighter, only available on level 10)
Defensive Sweep [Player's Handbook II] (requires BAB 15)
Overpowering Attack ACF [Player's Handbook II] (requires Fighter 16)

Level 7, you'll stop at Hold the Line. Then you add some way to become large (Enlarge Person, Expansion, Goliath Barbarian's Mountain Rage, some such), enjoy attack of opportunity for anything your opponent does while smacking them upside the head and tripping them if they try to go anywhere.

Alternatively/in addition, you could also add Dungeoncrasher [Dungeonscape], Knockback [Races of Stone], Shock Trooper [Complete Warrior] plus Rampaging Bull Rush [Races of Stone], and perhaps some way to fly, and trip enemy and then smash 'em to the ground over and over again. That obviously hurts a lot more but might be excessive in many circles.
