water bong with as much water to smoke contact as you can get (percs, diffusors etc)...
i had a small pipe that was so harsh on my throat... now i have a few bongs to choose from as well as a few bubblers... i find that the water does a GREAT job at filtration not only for the smoke but for the ASH that may get into your lungs (for those who dont know about screens)... but never the less...
its always a personal choice...
my step ladder...
gravity bong (water bottle, foil, cup of water)
pipe
straight water bong with diffusor
straight water bong with diffusor, and ash catcher
straight water bong with diff. ash catcher, down stem, and 2 percs
now i run a vaporizer through my bong with an adaptor... i find it all depends on the high im looking for...
vape (good for my headaches)
bong (good for my body aches (back pain))
vape/bong (more clear headed and i dont feel as high (good for going out or seeing family and not looking high))
and if i just want to get fkd.. i'll vape... then take some huge rips on the bong... fwiw... i do about 1 oz a month sometimes more.
you can see my collection (no vape pics) if you search my name... ive bought more things but i dont have a camera anymore (gave it away didnt pawn it for drugs)...
but in all fairness... my double perc has coma a few guys and girls for a good 3 hours on my couch.... off of one good HIT not a full bowl

and these are people who smoke with pipes everyday...
