One of the main things I look for in a jerk bait is buoyancy. I prefer suspending jerk baits to floating or sinking jerkbaits. Floating jerk baits work really well on shallow rivers like the W. Carson, while sinking baits work better in deeper river like the M.F. American. I like to use a suspending jerkbait early in the morning before the dam releases water, or later in the day as the water drops. Don't be afraid to use bigger jerkbaits for trout too. I've caught plenty trout on the Pointer SP65!
Gotta be honest tho, I haven't caught many fish on jerkbaits this year.. probably less than 20. I've been using mostly spinners and spoons if I use a artificial bait, otherwise the good ole night crawler. The reason being is I've had enough practice on certain rivers that I'll usually only use a jerkbait on the north fork, the south fork when shallow, or creeks. They work very well on small river/creek trout!
