I am not sure about the taste. I do not get any leftover or waste with it. I had a hard time desiding etween the bell curve and vap globe. What i can down with was that i didn't want to attach to a bong and to be pure unfiltered smoke for best taste and potency..
i have both a hmk curve and an oil dome love em both to be honest but the dome gets way more use but unless you have an open dome (mines closed) it can be easier to take a bigger hit on the pad but i really cant decide between the two to be honest!
maybe i'm ole school. but i like a nice bong with a small bore and a 14mm bowl with a titanium screen and i'll light it with beeline. i'm not into oils, only bubble. but you can't get those clear domes without the screen. :)
I have been smoking my kief out of my 3.5' glass bong using a magnifing glass to light it with the sun! Tastes nice and hits hard. Probably nothing new to some though I like not using a flame when possible.
