The 1 ounce filet is the best burning lipless in the industry.
The only improvement that I can see would be beneficial is to change the hooks to equivalent hooks with larger barbs. Fact fact that the bait is compact and weighs 1 ounce makes a situation where their head shakes are more effective at throwing the bait because of its weight. I’ve verified this by switching the hooks out on mine and ending up with a better landing ratio.
