Here I go again, please don't hate me but I do like discussing this type of thing
As you said, this one really depends on how far you are into the game.(Mid lvls, Maxed, Going 120/200m), so I'll just add some info that maybe you could add on the article or just to help our fellow clan members.
Protean Logs - Amazing if you have a Firemaking brawler. Protean logs+ FM Brawler + BXP from BA = 3m/hr xp. The downside, you need to do it at the wild, more precisely Mage arena bank lever. Don't ever use it for fletching, just a waste.
Cogs & memories - Totally agree with you. Completely useless
Traps - If you are maxed and planning on going to 120 or 200m, those on crystal chins are unbeatable, you can get 2.7~2.8m xp/hr while afking on DXPW. Worst part is finding a free world during DXPW.
Planks - They are nice since you can save money. But if you use monkey butler, you need to be near tick perfect to have some downtime between doing construction and waiting for the butler to come back with your planks.
Hides & Bars - Great if you are not maxed. Smithing can be expensive when not doing rune 2h/legs. Same goes to crafting.
