I like the FM mains with the 3/4 groove. The Clevite performance bearing is a full groove and I don't like the idea of the reduced bearing erea and extra oil of a full groove bearing.
I do like the Clevite rod bearings. If I remeber correctly, they have a larger selection of performance, narrowed and chamfered bearings then FM.

any of the name brand performance bearings will be fine. More important is machining, clearance, oil volume, oil type, detonation prevention, etc. The most expensive exotic bearings will not cure any of those.

Jyrki, if what you are doing is working do not change it.
