I've been trying to get diamond picks with silk touch sorted to my first hotbar slot. I've used <silkTouchPick id="diamond_pickaxe" data='{ench:[{id:33,lvl:1}]}'/> in InvTweaksTree.txt and sometimes it will work, but only with unnamed pickaxes (possibly pickaxes that haven't ever been used in an anvil). But also, sometimes it just doesn't work at all and won't find any pickaxes regardless of their name, work value, enchants, etc.
