Which type and size treble hook do i need to get for the regular 1/2 oz lipless crankbait like the trap or super spot?  Also, who makes the top treble hooks?

#4 or #6, sometimes a combo of the two...Usually 4's will be fine.

Try Gamakatsu Extra Wide Gap or Round Bend hooks, Owner Stinger 31, or Mustad Ultra Point Triple Grip. All three are good. I prefer the Gamakatsu hooks.

Some people like to put a dressed treble on the tail, like this-

X2.  I like #4's Gamakatsu Round Bend or EWG's front and back.  Some brands come with #4 front and #6 rear.  I'll leave the #6 on there until I see how it works, but usually end up changing it to #4.  Some guys go a step further and put short shank #2's on their 1/2 oz lipless baits (including world #1 Kevin Van Dam).  Hard to argue with success.

I use owner ST trebles, Imo there isnt a more sharp hook for the money. I get them at Janns for 3.97 per pack.
