go with an open centered valve, make sure you put a relief valve on the system, if the speeds are too fast you can put an adjustable flow control to slow them down.

I'm sending you an email in the morning with some schematics, part numbers, diagrams, and the information you should need to get everything set up. I hope it works out for you.
For everyone else, just be careful when using open and closed center valves. If every valve in the system is an open center, then nothing will happen when you put the power on. Hydraulic fluid is like electricity, it takes the path of least resistance, therefore it will flow through the open center valve that is not doing any work.
Secondly, if you looked carefully, he is using an hi/low Haldex pump. This is a great pump for hydraulic cylinder circuits and one that should be seriously considered when designing circuits. In his system, the high low pump should allow the lift cylinder to be raised quickly with no load, however if the loader is full of trees, still be able provide the grunt to get the loader up. Basically the high/lo give you fast speeds under low load, and slow speeds under high load(with lots of power).
Sorry to sound like a lecturer, but I just finished listening to professors for 6 hours a day for 16 weeks, so I believe they have infected me with something.
Good luck with your hydraulic endeavors! And remember, always use a condo....I mean relief valve!
