I don't know which one to recommend
I assume they'd be looking at both categories, but I originally used 2174 at the time and have just stuck with it. I'm in the regular HCP stream - if you can get into the French it goes much faster apparently. Note that it's pay-for-play - as in, its a CAD$1500 fee to process a OINP which why I'm totally loving this situation where I'm possibly 2 points from getting an ITA, but I've blown the money because I can't wait forever. OINP takes a lot longer than 60-90 days - it took 60 days from submission to move me to 'assessment', and based on MyImmiTracker, I've seen another 60 days to get nominated as well.
