Struggling to decide!

[flab2fab_rach]

I've been thinking about starting on a meal replacement diet, I have a large amount of weight to lose (around 9 stone) and just can't decide which would be better for me. I've been looking at:
Slim Fast
Cambridge Diet
Protein World Slender Blend
Celebrity Slim
Forza Diet

Can anyone please offer any help/advice? The reviews all seem quite good although only the Cambridge Diet has good before and after pics/large community on instagram etc.

Thanks x
