I would like some tips regarding weapon/tool making

Hello! I would like some tips regarding tinker's construct 1.12.2, basically I'm playing ⁠stoneblock 2 and I made a pickaxe using a spreadsheet that was lent to me in the discord server (Invar head, conductive iron Binding and stick ) and I think it's pretty cool, but I don't know what the "optimal" modifier route I should pick.

Should I add lots of redstone? paper is important? lapis should be my priority? Bc afaik, you can only have so many modifiers on a tool/weapon and I don't want to bottleneck my pickaxe by adding the wrong modifiers. Thanks in advance!
