How do mass and moment of inertia affect cylinder acceleration on an incline?

[zhenyazh]

hi
my question is fully attached as an image.
for cylinders with the same mass i know how to sort them.
the smaller the i the faster it will go.
but what happens if i have combination of change of i and m.
i guess i will need a less intuitive approach.
can some one tell me how to do this?

thanks
