I was just wondering what hook sizes yall use for plastics worms,lizards etc

Depends on thickness of the plastic and the gap (each brand is different). Can be anything from 1/0-9/0 but generally it is in the 2/0-4/0 range.

So does size really matter????

Yes, of course it does even though they say it doesn't.

1/0, 2/0 and 3/0 are my favorite sizes.

Heavy and light wire hooks can make a difference so use the ones that will better match your bait and presentation.

Weedless hooks can be excellent choices when fishing in heavy structure.

I mostly fish 5" plastics and larger, up to 9". I always have 3/0, 4/0 and 5/0. It's a wise decision to have a full arsenal just in case you need to alter your setup. Buy a few packs, and after a few trips, you'll know which hooks you like to use most.

Make sure the hook's gap is enough to get through the plastic and into the fish's jaw. I recommend a gap at least double the diameter of the plastic.
