your bowl in my exp depends alot on two things, your pref and your tabacco.
your pref, well i cant tell you anything about try both stick with the winner, as far as what your smoking. some brands and even flavors have alot more juice then others, same taste better dryer or more moist. i would look at the review section or ask in here about your brand or flavor to see what the community thinks about what bowl would be best for that particuler one.
as always trial and error is the best way to find out, i dont think the hookah itself makes a diff(never did for me as to what bowl im using)
