Firstly, thanks for putting the question out to the hive mind!
In the interest of individuality, I am going to say have a look at what everyone else has done for ideas, but don't limit your thinking to following a particular path. There is a lot information out there and a lot of different ways of doing things. Materials and construction techniques evolve, as do the electronics and deployment methods. Rocket builds are also very individual, even with the same kit as a basis.
So, at the risk of being controversial, I suggest you look at the various techniques and variations that are out there. Then think about how it will work in your build. Make sure you work to your strengths and skills for the build to improve you chance of a positive outcome. So really think it through, figure out what you think should work (especially for off-nominal situations!) and then put it out to the collective mind to see what we think. Sometimes we don't know what we don't know when building something, and a design review is such a good part of a successful build and nothing to be too afraid of.
There are a lot of opinions out there on lots of things, including dual deploy. Treat any criticism as constructive, design what you think will work and make the build yours.
If you have any clever or different ideas don't be afraid to consider them either. If they won't work then drop them, else keep an open mind
