What size hook to use for berkley 3.6 inch Max scent flat worm ? 
would a 1/0 vmc spin shot hook work ?

I use size 2 nose hooked.

Right or wrong I use a size 1 spin shot by VMC

Nose-hooked also

Try a Spearpoint #3 Drop / Shot finesse hook of the small Gamakatsu drop shot hook, its a #2. They are perfect for the smaller minnow style baits and pin the fish perfectly. 

 

#1 or #2 Gami split/drop or trokar DS

Hayabusa Spin Muscle #1

 

Truly the best wacky/dropshot hook I've ever used.

 

Bonus: it can be Snell-ed for dropshot rigging, similar to the Nishine DS hook. Absolutely perfect hook orientation every time.
