How long do you ride at a time? If over two hours at a moderate pace or better, or you just do one hour rides at an all out effort, then you'll probably benefit a little by putting some carbs in your bottles. And take a swig every 10 minutes or so. Don't make them sickly sweet though. I only put about 100 to 150 Calories in my bottles unless I know I am going to ride extremely hard for a long time.

Also if you are doing long rides, you need to learn what your all day long power is. And you don't need a power meter to do that. It's just a level of effort that you can ride without tiring. When you are at that level your body will be resting so to speak, so it will be ready for the next hill or hard effort.
