ummm, you know the RG value limit is 2.43 - 2.80 ?? coverheavy ball still need to within that range. And by just looking at the core shape and pics from the manufacturer is quite deciving. Coz the RG value is not just base on the core, I don't know exactly how to measure it but I know its including the cover, filler and core. To answer your question, there shouldn't be any noticable difference, if you believe in CGNOMADDAH.
