Stromsinger, seeker of the song or sublime cord?

[Deca4531]

]So my bard is about to hit lv 10. At current I'm bard 5 stormsinger 4. At this point I have 3 d send options. Either finish out stormsinger (http://dndtools.eu/classes/stormsinger/) or pick up seeker-of-the-song/ (http://dndtools.eu/classes/seeker-of-the-song/) to gain a few more useful Bardic songs and a few Bardic attacks songs that arent too bad, or I could go sublime-chord/ (http://dndtools.eu/classes/sublime-chord/) which doesn't really do anything with my bardic music but really pumps up my spell count and gives me up to 9th level spells.

I was thinking that if I went with sublime cord and paired it with the reserve the seats from complete arcane then I could be doing up to 9d6 each round in a variety of line, cone, and direct attack.

Which reserve feat is that?

Can you manage two PrC?
Take Sublime Chord at level 11 (and maybe 12). Then take the rest of stormsinger, advancing Sublime Chord casting?
It's a little cheesy, and the line about advancing casting from other classes changes from PrC to PrC.

What worries me for this are the prereqs. Have you been building toward both PrC from level 1? (3 technically with Stormsinger added in)
Sublime Chord requires a number of skill ranks many people don't take, while seeker requires a feat that's generally regarded as a waste.
