Whale ship equipment

[GeistX]

Hello! this is my first time posting here!

So recently i just collected up to 7000 whale medals. The question is, should i just grab the 7000 slice necklace, or collect up to 14k medals instead to grab the Neutral necklace? I wish to put it on my Lycoris (Miko) since she has 2 slots, and the other 6* is one slot Viola. I know the equipment is beneficial to Slice type, but i just couldnt wait anymore. Or should i be more patient? haha i cant decide

edit: necklace, not earrings XD
