No idea on the weight.
I don’t have plates yet either.
I’d probably keep it as light as possible.
How much does it weigh and how much are you adding? I like qore.

In that case I would go with a slick carrier or minimalist. Spend your money on quality carrier and add as you find what you like.
Lots of reviews:
