Innovation is dope, but end of the day, it's all about airflow.
I came out the gate talking shit about SB & Illadelph - especially cause of their egos - but using the same HMK oil dome, the SB & the Illadelph for whatever inexplicable reason definitely rip cleaner than the Toro or the HVY.
That doesn't mean they look better - or that they're tougher pieces as far as durability - but if you're talking about delivering rips, they do not disappoint.
That said, Ghost's tubes are some of the best looking pieces of glass art I've ever seen. I was over at Suite G (the dude who innovated the tree perc & handled a lot of the US Roor stuff after Sheldon Black split) a year or two ago and he was showing me the alien fetus chambers that Ghost sent him - WOW - very seriously awesome shit.
And yeah, the $10k illadelphs are absolutely outrageous rip-offs - but their glycerin coils are dope and their downstems are some of the best.
roor and sheldon are old school.... hardly any innovation...
now check out all the sweet things companies like toro and sg are making... shit will blow your mind.

the really long threads you should start from the back as thats where the most recent stuff is. like that toro thread is 4 years long, so all the stuff at beginning is ooollllddddddd (but still sicker than a roor).
lol roor and sheldon dont have shit on any of those tubes
