In the summer, especially during the day, fish don't want to move much and it is necessary to get a bait close and keep it near them longer. I love Senkos. The bummer is that when I am fishing in 20-25' of water and it's 100 degrees I am not very patient.
Anglers... I introduce you to the Pogo Stick. Its a Senko rigged with an o ring, a 1 or 1/0 hook and a small weight in the butt end.
In the pics you will see the Pogo Stick. Use one of those Senko contraptions to put an o ring on your bait. Then put on a #6 plumbing o ring. Then, insert part of a paneling nail in the butt end (push it in all the way. I Just left it out so you can see it). You can also insert a rattle if you like. It works well in stained water.
You can purchase the o ring and paneling nail from a hardware store cheap.
I recommend a 7' spinning rod with 15lb braid and a 7' fluorocarbon leader.
The cool thing about this bait is that is sinks faster, when it hits the bottom you can drag it or bounce it softly like a jig, on humps, down points, through trees and you can fish it all the way back to the boat. As you know, normally a Senko is only good on the fall. This bait fishes really well on long, hot summer days, when just sittin there is unbearable.
Peace and Tight Lines,
