I used powerbait exclusively for a while. Mainly because I don't know anyone in the area to help me out & had to learn on my own via reading or by talking with other guys at lakes. Powerbait was easy & convenient, plus I ended up with a ton of different kinds/colors after a local fishing supply store had a powerbait sale, so it's what I started with & solely used for a period of time. These days, at least for the majority of the time, my preferred method is spinners. But not going to lie- I still fall back on powerbait. I mainly use it to give me a chance to sit for a ten to twenty minute break to smoke, slake my thirst, & maybe eat something, as when spinner fishing I am constantly on my feet moving around whatever lake I happen to be at.
When I do use powerbait I have had great success using a combination of the power egg that's orange with glitter on it & also the half yellow/half clear garlic scented power egg. Sometimes I switch color on the half color/half clear garlic scented power egg but generally keep the the orange power egg with glitter on it, although I've been known to switch it out for a green color too.
