The smaller grip is G5 and and the bigger grip goes down to G2 right? I'm talking about Yonex rackets. I need to choose a grip size and I want the lightest one, thank you.
I dont think the grip size affects the weight much. The bigger the grip size is, the bigger the empty space in the handle becomes.. But I suggest you to get a G5 because some say that it's still lighter than the rest, which also means.. it's more head-heavy.. G5 feels the best too.
If the grip size doesn't suit the size of your hand, it won't do you any good. Having the correct grip size will be more benefit than saving that tiny bit of weight.
