This might sound "boring", but there's a lot to say about going Rog3/Ftr12/Invis5. With the TWF feats and Greater Focus/Spec taking up the bonus feats, you have 7 attacks at +2 attack and +4 damage, plus a potential +5d6 per attack sneak attack. With +19 BAB, you don't have the "flurry of miss" problem that plagues rogue TWF'ers.
Basically, your offensive capability will be huge, though your AC will be pretty low.
