I received my Skinny4 when i got home 3 weeks ago. That bait caught every fish that got to the boat October 10th, and every fish that didn't quite make it to the boat. The Skinny3 has a 3/4" body, and the Skinny4 has a 1" body. That Skinny4 will remain my mainstay in Inland Salt, hands down. If I only had 1 mold, it'd be the Skinny4. If I had choice of only 2 molds for the Salt, Skinny3 and Skinny4. The specs on my Skinny4 are... 1" body, 3" of taper, and slightly rounded tip. That bait and the Skinny3 are UnStoppable.
