Decent 0.28g BBs. Get out in the field with it, play, get better, then decide what might need upgrading. Seriously.

As above, don't touch it until you're not happy with it. First thing you should consider is your ammo - see if your hop can lift .25s, 28s and then .30s. At a minimum I would use .25s for woodland.

Typically getting a consistent lift on .30s means looking at a flat hop, but this is not always the case. Even so, that's getting way ahead of where you should be thinking.
