I see.... well the thing with TWF is while I love it, I have played a fair share of them (though for some reason, I haven't played a two-weapon fighting swordsage.) so I want to try a two-hander; but at the same time, the dual wielding warrior calls to me.. and I just recently found this homebrew weapons... which seems to fix some of the worst problems of TWF.
[spoiler] Twin dao
One-Handed Martial (dao) or Exotic Melee Weapon (twin dao)
Damage: 1d8
Critical: 18-20/x2
Range Increment: -
Type: Slashing
Weight: 4 lbs
Cost: 10 gp (dao) OR 400 gp (twin dao)
Special
The twin dao is both a single weapon and a set of two weapons. Both are masterwork, and fit into the same scabbard as though they were a single sword. Twin dao must be used as a set; attempting to use a single twin dao as a normal dao gives a -4 penalty to attack rolls due to the strange balance the swords have. A twin dao may, however, be used as a single sword when held together. All feats that apply to normal dao (such as Weapon Focus) also apply to twin dao, whether used as a single sword or when used as a set.
When used as a pair, one in each hand, however, the twin dao show their true colours. They are perfectly balanced for wielding in two hands; while they are one-handed weapons, they can be used as if they were light for the purposes of two-weapon fighting, but only when paired together. Additionally, the wielder may add their full strength bonus to damage to both dao as if wielding them in their primary hand.[/spoiler]
I also have been entertaining the idea of a character who followed Miyamoto Mushashi comment on fighting
Two weapon for many enemies
1 for single enemies.
But I am sure that would be extremele feat starved and gold hungry.
Edit: Actually upon a closer reading, the twin dao work extremely well for my idea, I would only need to select power attack, and I wouldn't feel I am loosing upon my build when using single attack strikes...
