Senkos are my number one go to bait. I prefer using a Gammy 2/0 offset worm hook. I always leave the tip exposed slightly for better penetration. There are times I go weightless and there are times I will add anywhere from a 1/8 oz to 1/2 oz texas rigged bullet weight. If I was fishing ponds like you do mostly, I would always go weightless, since the ponds don't experience high levels of current. The natural weightless drop of a senko is dynamite in fairly calm conditions. On the river, I will add a weight to work to my advantage with current. I mostly swim the bait, with occasional drops and sharp jumps. There are situations when I want to use a senko deep (did this on Nickajack), and I will fish ledges with it. I fish it just like I would a jig. At times I believe its better because of the slender profile, and its something deep fish don't see a lot. I typically use the 5 inch version for these situations.</p>
Senkos can also be effective in small streams (upper PR River, Flint River, etc...)... but I will turn to a 3-4" version of the bait, for a smaller profile that fits well with the clearer waters. I like natural colors.</p>
Also, I don't use Yamamoto's baits anymore... they simply can't hold up as well as others, and are very expensive. I am sold on Mann's Hardnose Freefall in Watermelon Black Metal Fleck color. However I only find it in the 5" version. Yama makes the smaller versions.</p>
