Cycling carbs and calories can be very useful if you know what you're doing. But its also easy to stuff up and eat too few or too many calories for the week, which gets you nowhere.
If you have a predictable schedule, can count calories well and have a good feel for your daily needs it can work. You'll always be thinking about food to keep track, but that might not bother you. What you'll tend to find is most guys who make it work have done it for a few years and made enough mistakes over time to figure out what works for them.
If you get it right you can gain weight really clean over time, or lose fat and spare muscle really well. Good luck with it.
