If you're supercharging, I'd definitely swap the bearings. I'd be doing the mains too.

There are supposedly oversized Rod Bearings available for the S65 or S85. This, or a company is still in development of them. Let me reach out to a friend who is a master technician of the S85 and see what he says.
As far as the Cryo-Treat bearings from VAC, I would not recommend them at all as they are adding extra unneeded material between the crankshaft and bearings. I have a few reputable friends who have done tests between the regular bearings and VAC Cryo-Treated bearings and the coated bearings looked like they had 20K miles after only having been driven 5K. Said friends also conducted these tests with multiple oil types and other variables to see what the best remedy was for treatment. It's just not worth it. The real issue lies with the bearings being too close to the crankshaft and not allowing enough oil to passage through and dissipate friction.
