The real positive point is that the pressure in the circuit remains at a low level when no function is activated. To my knowledge, no other model manufacturer offer this advantage.
I haven't made a test "in field" now, but the equipment forces seem to be way enough for serious digging.

Sorry for the long post, but I wanted to tell as much as I could about this model. I hope this helps
I like your review!
Please let us know how the castings stand to use and abuse.

In regards to dual stage hydraulic system;
- exactly what I have in mind for my project - if I ever get to that stage instead just pulling the trigger on the prebuilt model.

I think that the benefits of such system are in reduced energy wasted while the hydraulic system is "idling"... I'll have to try something similar with my hydraulic parts soon.

Oh, I nearly forgot to address the weight issue.
I know that it is very hard to pull a loaded trailer. 27kg, I bet the trailer has at least 3 to 5 more and that makes really heavy load. I don't fancy trying to tow that on a loose surface. But, isn't that what is fun? Building your tractor truck with large reduction rates, having decent amount of power, building and "cheating" the drivetrain to make it - yeah, that sounds fun to me!
