A roller bearing wil be far superior to any ball bearing. JFP's claims are here say with zero empirical data to back it up. When it comes to IMS bearings, you have to consider who's supporting what product and why.
He claims that the roller bearing is "infernal", yet provides no data to back that up. Meanwhile, he claims, through suggestion, that LN bearings and the "IMS Solution" do have that data (where is it?). If he is simply referring to online testimonials, there are plenty of failed LN bearings to read about (though those were all due to left over debris or installer error), yet I can't find any reports of failed Vertex roller bearings...yet.
I'm not taking sides (I have an OEM dual row and it will forever stay OEM dual row), just saying that all options should be weighed and don't fall for the bullying.
The point? Take everything you read with a grain of salt and consider who is pushing a suggestion and why.
