Trying to decide between these two bubblers. My primary use will be for flowers. I have various "mini" bongs, but I want something even smaller, mainly for convenience/portability (think throwing it in a small backpack and going on a hike or over to a friend's house). Primary use will be for flowers. Small, snapper bowls. Flavor doesn't matter much to me, I value filtration and a smooth smoke above all else. Next on my criteria list would be portability. As I understand it, the main difference between these two pieces is the diameter of the main can. Does anyone have experience with either/both of these pieces? Is one noticeably smoother than the other? I've heard from one source that the Nuc was smoother despite the smaller can size. Anyone able to confirm/deny this? Any experience you can share is most appreciated! Cheers!
