Maybe this will help explain it. Could not find the correct CFM diagram to do this justice so I just winged it, hope this helps. Basically think of smoke as only so much being generated when you take a draw on the hose. Regardless of how fast you take a hit, the smoke generation is fixed. Therefore a massive hit, when mixed with a large amount of air, just washes the smoke out. In contrast, a slower steadier hit will take as much smoke as the shisha generates and thus allows you to accumulate more smoke using a smaller volume of air. At least that is how I rationalize it to myself, I like the large hoses for the volume of air but, you should still draw on them slow.
I remember someone taking about taking three quick puffs on the hookah to get it going and then taking a longer draw. All about maintaining a steady draw and taking just as much, not more, of what your tobacco can generate via smoke.
