Pats is OK if you like to weld nothing.
QH is good if you have all your and your neighbors tools made with standards.
EURO HOOKS are not QH.
Weld them on lower arms and that is all. You need not to chance your tools.
You can use both cat1 and cat2 tools by balls that have drilling for cat1 or other for cat2 size.
You can adjust them from the cabin very easy too.
Some welding job.
I made at first universal QH but it is too heavy.
Then I used EURO HOOKS
I made links from cabin to hooks and rope for hydraulic
top link. I have one feet long spring inside the rope keeping it upwards. That is fine.
QH weight is 50 kg, Euro hooks and my linkage 10 kg.
Here is some video of my works
