2nd round of insanity or turbo fire?

Hi everyone,
This is my first time posting on one of these message boards but just wanted some advise!
I'm a 24 year old female, weigh 161 lbs and about 5"6, i've currently got 3 days left of my first round of insanity (woo hoo!) and ive currently lost 8lbs but not many inches at all from the places ive measured (hoping this just means i am losing it in places that i havent measured!)
Im looking to lose the rest of my baby weight (I have a 1 year old boy) and need to tone up a lot!
Before I fell pregnant I lost 2 and a half stone in a year just doing cardio at the gym. I only have 7lbs left til i'm at my pre pregnancy weight but i want to lost another 7 lbs after that.
I'm currently undecided whether I should do another round of insanity after a week off or start turbo fire?
I am vegetarian but sticking to the 40/40/20 ratio and netting 1200-1400 cals a day. My main goals are to lose this last 14lbs and tone up a lot all over but mostly my 'mummy tummy' lol.
Thanks in advance for any replies :-)
