Best items to make with steel bars (Members)

I’m curious, if I was to use my steel bars and make them into something, what would be some of the best things to consider when members release?

Cannon balls, arrow heads, knifes, plate bodies?

GP vs Training supplies

Thanks

Cannonballs for Gp.
Arrowheads for fletching XP and smithing xp
Platebodies for fastest smithing XP
