No idea about these, I had some by another brand years ago (Slo-Mo, Slo-Fall or something like that), but I bet these behave the same. I tested them by dropping one and a live crawfish in a tank side-by-side. They fell at the same rate and looked REALLY good with a crawfish trailer.

I caught a few fish on them, but be warned, you better have your patience cap on tight, because that's a lot slower fall than you realize. Put your mindset on "weightless wacky worm" and not "1/2 ounce jig" and that will help wait on the fall. Fishing them in the wind was tough too.

The ones I had didn't cast or pitch well either, but maybe these new ones have solved that.

Fall rate is key with jigs as mentioned above I have found that when the bass want a slower fall rate a good trick to slow the fall down is to wacky rig a 5� Senko for the jig trailer

BUt but I thought the fish had to look the jig in the eyes to intimidate them before eating?

The baits u r referring to were made by Roy Greer and were called Penetrator Jigs. The jigs were about the size of a 1 oz jig and the heads were made from hot glue. They had an extremely slow fall rate and were deadly on bed fish. I still have a box full of them.

Every jig has at least one eye.

I consider myself fortunate when I get to fish with a local stick who does well in tournament schedules around here. He's an extremely versatile and detailed angler especially when it comes to jig fishing...none of his jigs have eyes....NONE ! I have learned there are other aspects of jig adjustment which will help make a difference at weigh in.
