What size hooks are good for lipless crank baits and square bills 

Depends on the size of the lure and original hook size that come with the lure.

Idk the exact hook size but it’s a half once bill lewis trap and medium size square bills 

#4 or #6 will cover most of what you need for those size baits. 

#4 shorts

Tackle Warehouse and Bass Pro have the hook sizes listed in the description of the bait.
