I've done both as well. The old WW was ne from about 15yrs ago and I got on famous with that but have been doing Calorie counting this time.
My daughter has lost all her wieght by doing the new Pro points WW and swears by it...so it's what suits you really.
The general amount of Pro Points is 26 -29 per day and an extra about 40 per week but it is all calculated on your weight and height.
