Just use commons!
No need for sets until much later in the game, unless there is a very specific something like KB/KN you might want to get.
IMO, it's just a waste to do more than plain IOs, and upgrade here and there, until way later.
On this version, it will be easier to move them around, but still.
Just my pennies.
Agreed, don't waste money on sets until your at end game. They arent needed for leveling.
