Here's a neat little trick - Next time you're at your dentist/orthodontist, ask for some of the rubber dental bands (tiny rubber bands) used to hold the wire for braces to the post on the tooth. (My wife gets them in multiple colors for her younger patients.) That band is about the same thickness as your Senko (or Senko-type bait). Slide or roll the band where you like to rig your bait with the hook exposed. (For "wacky" rigging.) You'll then want to slide your hook under the band instead of through the bait. Your baits will last 10 times longer and the rigging will not deter from your hookset.
On a side note - If you haven't tried a Jimmy Edge "Speed Fall" worm, you might want to. They're sold in 4.5", 20ct. boxes locally, through of all places Walmart, and are identical in every way I can find to a Yamamoto Senko, except for their $2.86 price tag per box. (The most salt I've seen poured into a bait like a Kinami or Yammy.) I don't know Mr. Edge other than his reputation, and would sooner take a beating than fish a soft plastic, but I am sincere when I tell you it is a local "secret" bait. FWIW
