Rolo & senile I have to agree, while I've had limited success with senko type baits I've won a tournament & had tremendous success with a Texas Rigged Zoom Trick Worm with a nail in the tail. This setup will fall slowly & horizontally like a senko but it has a smaller profile which apparently makes a difference since the 2nd & 3rd place anglers were throwing senkos.

I hate senkos so much I bought all the stuff to make my own.  Between a buddy and I we have found a formula that replicates a senko.  I actually prefer mine better then a senko.  Plus they are about .10-.15 each.
