I bought 2 huddleston weedless 6". and im looking on the bottom of them, and notice there are  tiny holes in them. the one is under the bottom jaw, the second is under the pec fins and the other is by the back fins. not the tail fin. what are these holes for? are they there for hooks to be attached? or are they there for molding process?2 of the holes go into the lead inside the baits like a space to add trebles. any info would be great. :-?

It sounds like an issue from the pouring process.  I have had holes in my 8in hudds.  They aren't a big deal and shouldn't pose a threat to the bait, but if it bugs you, contact Ken and he will replace them for you.

Prety sure those holes are there from pins used to hold the internal rigging in place while the bait is being made. They serve no purpose once the plastic has cooled and the pins are removed.
