When it comes to the hammer the head determines the mining level and some of the mining speed and durability. The plates also determine the speed and durabilty.
My hammer configurations is usually Steel/Cobalt head, One plate Steel/cobalt the other plate paper and the tool rod is Thaumium. Thaumium is kind of like paper but with more durability but only adds one modifier regardless of how many parts you stack. So a full Thaumium tool wont give you 3-4 extra mods like paper would.
I'll then put the Fluxed modifier (hardened level is usually enough), Fortune/ Silky, the rest is speed. If you opted for Cobalt head and plate you end up with quite a fast tool.
