Size Difference = How Much Smoking Difference?

[JoeCool87TC]

Within the same tobacco blend and identical rolling techniques, what kind of "smoking" differences will there be between a Robusto (5 1/4 x 52) and a Prominente (5 1/2 x 56)?

I have an opportunity to get a decent deal on some Prominente size sticks where I already know I love the Robusto size. Will there be big difference or will they smoke about the same?

Thanks!
