If you have a generic swimbait that doesn't track straight, try just putting the hook in the bait in a different spot. Usually this slight change the weighting will cause it to swim a little different and you can tune it to swim ok. I've also noticed that for some reason the bait tracks straighter and straighter the more you fish it. I've only throw mine a few times but it has worked well for me with a 6-1 and a 7-10 at Rancho Seco on the 7.5" bait.

For Perris, I recommend the kitchen sink. That lake gets pounded by trout chuckers. Throwing something new and different would be a good bet. I'm sure those fish have seen about 10,000 ospreys by now.
