New con rods from MAP or keep the stock ones?

R&R rods are lighter than stock @ 400 grams and are bushless like a norton rod, so less small end weight? - stock ones averaged out to 420 grams when I weighed em. Map are heaver @430 grams, Hepolite marginally heavier yet @ 432 grams. LF harris say they're OEM, but nobody lists a weight, and I can't find 'em stateside. I'm thinking whichever way I go it's like 10 grams difference totally, probably less than that on the little end... so no big deal? total over both rods would be 20 grams more if I went with the steel MAP rods. the difference would be 40 grams less with the R&R. If I guy was to roll the dice and just run em no rebalance, would you go less or more weight and why? Balance factor goes down when the rod weight goes up and vice versa... assuming the crank was actually factory balanced to 85% heaver rods would move it closer to 80, lighter rods closer to 90... any thoughts? Also, im more inclined to not care so much since the rods that were in it were 6 grams apart to begin with...
