Hacking sky3DS+ micro SD recommendations?

[Darkness63]

I heard sky3DS is pretty picky when it comes to micro SD's (things like size and brand) - not sure if they fixed it on sky3DS+. But anyway... this is a question for the sky3DS+ users from this community: what micro SD do you recommend? can I use a 64GB or 128GB micro or should I stick to 32GB to stay safe?

I want to hear you guys' recommendations so I can buy the right micro.
