I have never done that, and never will, I know what they like, so why play?
Its always worth a play if there is a possibility you may find something they like more.
One of the first lakes I concentrated on I was told that they generally liked mainline baits like fusion, I tried those with another bait and after a while noticed I was catching a lot more on the other bait which was CC Moore's Meteor then switched to them permanently. Another lake I was told Cell and Fusion were doing well so tried those along with a Premier Baits recipe and was doing better on the new bait.
So were probably the opposite, I've always done it and I probably always will
