The dual row bearings seem to hold up better than the single row and from what's I've read, the also give some warning before they fail, as opposed to the single row that tends to give no warning before they grenade.

LN has not had a single failure of the ceramic dual row bearings and only a handful of the single row. The "ultimate solution" from LN only applies to single row bearings, the dual row is so robust they don't make a "solution" for the double row.

My car was built in 7/99 so I'm hoping I have the double row. At 131k miles, I'm just going to wait until I need a clutch to replace the IMSB, but I do check the oil filter halfway through the oil change interval to check for metal and do UOAs to hopefully get some advance warning.
