Catalyst Redux

So, I can't seem to get some of these lines out of my head. This poem keeps rewriting itself. And here we go again.

This is just the catalyst for what comes next,
The breath before the scream,
The pause before the start,
Tension pulled to the breaking point.
Its the balance beginning to sway,
The calm before the storm,
The frenzy before the fall,
Its the dance, out of control.
Turn the key and wind us up,
The spring's about to break.
Let me loose and watch me spin,
There's not much more I can take.
This is just the catalyst.
The moment of truth.
Will you stop me here, or let me go,
Dark oblivion or bright ecstasy await.

I don't know which I prefer. They both have something I like. I think this one focuses more on the tension, whereas the other is more about the tensions possible resolve. Hmm...well, here's hoping there isn't another rewrite.
