Looking for a finesse swim bait head. 1/8 or so. Seems like everything has too big of a hook etc. 

Any ideas?

Scroungers are always an over looked option for keitech baits. Just my .02

Megabass makes a 1/8th head that fits it really well

I use the Keitech Mono Guard Jig Head in 1/8 oz - 1/0.

Oldham's makes a great head! It has a pretty stout short-shank hook AND a screw-lock. Dicks Sporting Goods has them for $4.49 for a pack of three. They have a double wire weed guard, but I cut it off. 

I prefer a 3/0 hook for 3.3 and 3.8s. Owner makes a great swimbait jig. It's the ultrahead inshore hook. Comes in 1/8 Oz and it's not too big for 3.3s imo. You could also use the Owner ultrahead round jig head. 2/0 hook, 1/8 Oz.
