No question the non-grooved lower bearing would be stronger, but it's going to take a pretty strong argument to convince me that outweighs the need for the rod bearings to have constant oil pressure.
I just got back from a trip to Summit racing where I purchased 2 sets of bearings so I can piece together a fully grooved set. I plan to wait a day or so until I get feedback on this before I open the second set.
