I'm looking to buy some jigheads (swim jig, flat eye arky and football)  and swinging heads. I'm looking for options with different hook sizes, light and heavy wire, etc. I've bought from elken lures and I like those jigheads very much. What are some other options?

Maybe Siebert outdoors can help you out. 

Cadman and smalljaw also sell jigs and are on this forum.

Siebert's stuff is EXCELLENT... I only got into jig fishing at all a couple years ago, and I buy the bulk of my jigs from him.  I can't say 'all' since I'm not above picking some booyah jig out of the bargain bin at StuffMart from time to time.

siebert has great options, great prices, great service.  if you want some really specific custom stuff, site member cadman can and will make just about anything you can think of and he's also a great guy to deal with.
