Got a little bit of a project happening right now, and it involves a group of 25th level characters. Hoping for a few suggestions on the following list of feats I'm contemplating to build the Ultimate Greatsword Fighter... the focus is primarily on hitting hard and secondarily on lasting long enough to hit some more. Let's assume all the ability and skill prerequisites are met. PHB unless otherwise specified (I think I got it all right); {H} means human bonus feat, {F} means fighter bonus feat, {E} means epic feat. Permitted sources are any WOTC book which is not campaign-world specific. I am the DM, so I'll entertain any and all suggestions that I happen to like. 
So here's what I'm contemplating:
Human Fighter 25
1. Power Attack {H}
1. Weapon Focus (greatsword)
1. Combat Reflexes {F}
2. Cleave {F}
3. Iron Will
4. Weapon Spec (greatsword) {F}
6. Lightning Reflexes
6. Improved Sunder {F}
8. Greater Weapon Focus (greatsword) {F}
9. Melee Weapon Mastery (slashing) [PHB2]
10. Improved Critical (greatsword) {F}
12. Armor Specialization (heavy) [PHB2]
12. Greater Weapon Spec (greatsword) {F}
14. Slashing Flurry {F} [PHB2]
15. Defensive Sweep [PHB2]
16. Martial Study (mountain hammer) {F} [BO9S]
18. Martial Study (overwhelming mountain strike) [BO9S]
18. Weapon Supremacy (greatsword) [PHB2] {F}
20. Martial Study (elder mountain hammer) {F} [BO9S]
21. Epic Weapon Focus (greatsword) {E} [CW]
22. Epic Weapon Spec (greatsword) {EF} [ELH]
24. Epic Toughness {E} [CW]
24. Epic Prowess {EF} [ELH]
Thanks in advance!
