I've been experimenting with the weighted heads from Hareline. I've on to the Sculpin Helmets. Sculpins are really cool fish. I kept two of them in my aquarium until they started eating me out of house and home. They would lay flat and motionless on the gravel at the bottom of the aquarium and then would dart out quicker than the eye could see to grab a guppies I was feeding them. The danged Sculpins would not eat anything that wasn't alive so I had to buy guppies. It was fascinating. They'd be laying on the bottom... I'd dump in some more live guppies and in the blink of an eye, the sculpin was where the guppies once was. They are fast! But because they don't really swim around much but instead lay in wait, I'm not really sure how to fish the patterns. I suppose they must swim around every once in awhile but the ones I kept relied on the ambush technique so they primarily stayed on the bottom. The heads are designed to keep the pattern flat on and close to the bottom so I'll see how they work. There are sculpins in some stillwaters so I'll give them a try this summer. Eventually, got tired of buying the sculpins live guppies so I released the sculpins in a nearby creek.
