Also got blackskull shield, green tower, flurry axe,fiery war axe, the staves and some others at 48/49. Not sure if any of these are actually good at this bracket tho and worth building around.
Because the BOA can get the incendiary ammo enchant, I would think the boa is better. I'm not certain on that, but the 1500 proc seems like it would outweigh anything.
