Do you guys prefer high risk high reward VS. decent healthy growth?

Say you did the math to perfection. You have two portfolio allocations and the best crystal ball money can buy. The crystal ball tells you that both allocations are winners but you have to go with one or the other now no backing out.

ALLOCATION 1: 300 – 400% guaranteed growth of any allocation put in over a decade period

ALLOCATION 2: 0 – 2500% growth of any allocation put over a decade

Which one do you pick and why. No funny business a straight answer please.

Thanks!
