Gwyn-
I agree with itsjoyful that you're routine looks great and maybe you want to cut down on cardio a little. What do you do for cardio? How long is your cardio sessions after weight training and on cardio-only days?
If you like doing cardio after weights, maybe you don't have to be as intense as the cardio-only days. That's just my observation. I know I'm a lot hungrier on weight days than cardio days (and I don't do cardio after weights, I'm too tired). I just eat when I'm hungry and it all averages out at the end of the week. From your stats, it looks like you're doing great and getting results. I'm scared of the weekend carb-ups too, but it's a very interesting concept. Fill me in on how that works if you decide to do it.
Otherwise, I'd say keep doing what you're doing if you enjoy it. Don't be afraid to cut down on cardio. I was afraid at first, but I didn't gain weight because of it.
