I didn't do the bird farm either but it was nice getting the +10 stone a little earlier than waiting until snowfield which is damn near the end of the game.
The Haligtree aids sections you can easily sprint through. It's only a bitch if you want to actually explore it and get the items, but there's nothing really worth clearing for.
D's set is good for your current area, and armor is kind of lacking over all in this game. I think it could use a boost for those who choose to invest in endurance.
I also get athena on my main attack if I'm doing a melee sword/claw run. Deflect will let you get in things faces much easier with more room for error as well. Zues/Athena boons for mutliple/fast attacking stuff like bow/gun is another favorite.
