Nitrous and Automatics

[C3L1CA]

Does anybody here have any experience with automatics and nitrous?

Last year I ran 100 shot once I hit 2nd gear in the 1/4 mile and now that I have an auto I would like to do the same thing. I would also like to use it to get on the converter if need be.

I would like advice on how to safely use nitrous to get on the converter and spray down the whole track.

These are the options I have found after my research:

1) Use both the FPR and EGR setup in DSMLink. That way the I was spraying last year via DSMLink with the FPR. However I don't know if I need 100 shot for getting on the converter and spraying a wet shot that low kind of scares me.
2) Get another solenoid and just wire up a button to spray a small dry shot on the line to get on the converter and run nitrous the same exact way I did last year.
3) Get an ignition based 2 step and just run 100 shot all the time once it starts spraying. This was suggested by a pretty quick guy on the dsmlink forums, but I'm a cheap bastard and feel like I could get a single solenoid and what cheaper than I could an ignition based 2 step.

Opinions?
