I think a rokit v5 bong would be better than other bongs for better filtration as well as denser hits because when I saw this video of perculators in action, even though there were around 18 holes, only the top was being used and the rest wasn't due to air rising.
The rokit bong has holes but they are positioned right in front of each other instead of on top of each other. This means that the smoke will have to go through each hole in order to get to the smokers lungs and being that its small it will have less air and more smoke in each hit.
This design probably also explains why it clears so fast as opposed to other bongs with percolators when they remove the bowl and let air in.
I will get one and I would advise others if smoothest and dense hits are what you want.
