Further to my other post, you will find that you make slight adjustments now and then for example I set the Master Bus meter to 12dB range because I am only interested in the high end on the Master.
 
You should set up some screensets for example I use...
1) Track View
2) Console View
3) Console view with the Master Bus effects open ( I use Voxengo's GlissEQ,PolyQuasher and Elephant )
 
Each time you change something to work how you want, save an empty project with all the changes so you won't have to do it again.
 
So to start a new project I open a template e.g. 'orchestraltemplate000.000' then I save it as 'orchestral003.000' for instance then every time I record or edit the project I save it as 'orchestral003.001', 'orchestral003.002' etc. so I always have several backups and I know that the project with the highest .xxx number is the latest edit.

Unless you routinely create songs that are all in the same narrowly-defined style and genre, you'll probably find track templates more helpful than a complex default project template.
 
For a long time I kept adding things to my default template, which made for convenient start-ups - for a while. But over the years my tools and techniques changed, and I found myself deleting or ignoring more and more of the preset stuff in my project template. So I started trimming it back, making it simpler and more generic.
 
For example, I had a specific setup for Superior Drummer that took awhile to configure from scratch, so I'd included it in the template. But then I realized that this standard setup was making every drum track sound alike, requiring further tweaking to SD for each song anyway. So I took SD out of the default project template and created track templates for it instead.
 
Each of these templates is named for the song I originally created it for, making it easier to choose one for a particular feel. (I use the same naming convention for custom effects presets as well.)
 

it also saves presets and screentsets as well.
for instance if you like your metronome set up a certain way like I like mine to have a 4 count before record starts.
and if you liked record mode to be over written rather than blend, EXC.
its not all about the track configurations. but you do bring up a good point about projects being different and one can fall in a certain peanut butter and jelly groove.  :)

All my template are blank. I start all my projects with a clean slate and decide what is needed.

What CJ said.... But then I do use track templates a lot.

even if you just create a template with your screen sets all set up its worth it to me.
I usually start out every project by going to preferences first, changing about 3 or 4 things.
then I go to screensets, I change almost 6 or 7 screensets to my liking, one for normal view(console in the dock)
another with the PRV open, another SS is showing midi tracks only, another SS showing audio only.
another for comping view, which is 2 tracks opened the width of my whole monitor(inspector and browser are not showing)
 
so im left now with a blank project but all my settings and screensets are good to go, this shaves off atleast 5-10 minutes off every project.
but even more importantly, it lets me start creating music right away, sometimes when we use all this time to set up, we lose a little of that creativity.
because don't we all just want to open sonar and start creating ?

I do have a chillout template which looks like the following
Drums
- RMV
- Audio track for percussion/other loops
Bass
- Dim Pro Almost Synth -> GR5
Guitars
- Audio tracks -> GR5
Keyboards
- Scarbee Rhodes piano
- Absynth
 
More often than not, I use track templates though.
