just go for an aerodynamic backslider, you dont really need that much simulation. Just keep it lightweight, and with a lot of practice you can get a consistant 20-25 second backslide.
Also remember to minimize any imperfections on the rocket (air bubbles when taping, etc.) to maximize the flight. And make sure that you have some weight fr stability; don't just build the lightest rocket as possible.

If I had to guess, I'd say ~40 seconds for the combined time...but don't quote me on that.

You can add clay to an end, change the fin size, change the length of the nose cone, etc.
For those of you who are using glue, what type of glue are you using?
