this probably won't please Jim as people might want to increase their orders (ultimately that is up to him for how much he can take anyway), but coming from someone who has all of the nets, I couldn't live without having both sides AND centre.
I have both the side nets and the centre net, and honestly unless you somehow are after 'looks' in your boot. Centre net is a necessity with the side nets. Centre net basically acts as an empty net for you to put stuff in like shopping etc. It also doubles as a perfect holder to put things BEHIND (up against the front of the boot and the net) to hold them in place, like big boxes as the net is very elastic and can act as a barrier.
The side nets are perfect for the stuff you want to carry in your boot ALL of the time, but they are not great for 1 trip deals as they are a bit too small to fit most things that you don't want to keep in your boot all year round.
Personally I use the left side net for a 1L oil bottle plus the subaru carry case. I also have batteries in there for my LED torches, plus 2 small LED torches and then a big LED torch. The right side net I have a bottle of quick detailer, a few microfibre polishing cloths and a special detailing cloth. Under this I have spark plugs and some garbage bags.
You would be a fool NOT to get the centre net (in a sedan as I can only comment on a sedan) assuming Jim can manage to fit all of this in etc. It's worth it in the end, ESPECIALLY if you have a rubber Subaru boot mat which is easily scratched by things sliding around.
Just my 2C anyway
