When twitching jigs, most anglers consider the 3/8 oz. and 1/2 oz. to be the staple jig weights. I myself use the 3/8 and 1/2 in most situations.
When rivers are extremely low and clear however, or when fishing small streams and sloughs, the 1/4 oz. jig is an essential option for the diverse angler’s arsenal.
When twitching this lighter weight of 1/4 oz. jig, a lighter line and softer rod are much more suitable. I prefer an 8.5-foot medium strength rod with a slow or moderate action.
For this setup, I use 10-pound braided line with an 8-pound fluorocarbon leader. This allows for very long casts with the lightweight jig.
The angler must modify their twitching method to suit the fish’s attitude in these conditions. My favored presentation technique in this scenario is a light twitch action with a longer pause for the jig to drop.
I have had success with both dark coloured jigs- and in dirtier water, bright colours like pink and chartreuse.
Good luck out there! Tight lines & BENT RODS!
