Hard to quantify hours. Start to finish each bait takes about a week, working a few hours a day on several baits. Rogues are a bit slower than warts for me b/c they are more individual -> more color changes ->more clean up, etc. When I shoot warts, I usually shoot a minimum of 6 each color, then work until all the clips on the turner are filled.
I have a problem with addictive hobbies...painting baits, hand pouring plastic, rod building, and most recently reloading ammo. I have no problem running out of time unfortunately.
