I tend to get a more follows in colder water than in the summer. The good news is that you're doing something right. Regardless of the water temp, the first thing I do is change things up. First on that list is the retrieve. In 60 degree water, I'd speed things up first. Shorter pauses, stronger twitches are examples. Not working, or not seeing any more followers? Slow down.
The second thing I do is change the size of my presentation. Smaller, larger, or even a different profile can be all it takes.
Lastly, I'll change colors of the exact baits I was getting follows on. You can change the order of how you'd do it, but if you're getting a lot of follows, or the ones you're catching are hooked on the rear treble, change is the answer.
