Looking for opinions and guidance folks!

I am now in the lucky position to own two Technics 1210 turntables with the upgraded Mike New extra bits.
One deck has the bearing and the copper topped platter, and the other deck (RobbieGong's one) has the bearing, bearing base plate and the ETP platter. Both decks have the same upgraded Micro Seiki MA-202 tonearms on them.
My question really is as the Mike New copper metal platter is heavier, do you think that would benefit more placed on the deck I purchased from Rob that has the baseplate also attached, as opposed to the deck with only the bearing attached?

Maybe nothing really in it, but would appreciate the knowledge gained by you guys who have gone down the Mike New path long before me...
