imo teak planks are more useful than oak there only a little bit more expensive than oak, and is alot more faster for me i personaly use workbench and use make all, less clicks etc and is still fast using demon butler to collect 24 planks keeping 3 sc hammers in inv and 1 saw 24 planks can make 4 things at 6 planks needed each oak - carved oak tables teak - magic wardrobe both need 6 planks ea making it fast sc hammers last roughly 50k in construction (bought 99 con few days ago currently 94)
