I think if you follow the 1/3 superfree with every meal, it is unlikely you would overindulge in carbs. It tends to balance it out I think.
I do mostly extra easy and it doesnt seem to affect my weight loss.
I try to get as many healthy carbs in my diet as possible. This means I choose wholewheat pasta/rice over normal pasta etc, where possible. Sometimes I have been lucky neough to find wholewheat couscous as well. I also tend to leave the skin on my potatoes when making things like sw chips etc for the extra fibre. Little tweaks like this can make quite a difference.
Of course at the same time, when intaking a lot of fibre you also need to make sure you are drinking plenty of fluid. i.e. water or a sugar free drink of some sort.
