Ah, now where is the "suddenly, hoes" config 
{it made the hoe weight pretty much outweight everything else}
Although i prefer the GregTech way of nerf, which pretty much makes scrap 60% of what you get from a box.
Also, instead of nerfing the scrapbox, you should nerf the scrap generation by blacklisting cheap materials like cobblestone, snow and any of their derivatives, like GT does.
Wooden hoes already have nearly double what all other wooden tools have for a drop chance, and the wooden tools are the most likely thing you'll get from a scrapbox in normal IC2.
