I took the DLX M out to my friends last night with my smallest j-hook and ended my 1-week t-break. Two smallish bowls obliterated me totally. The second one, I thought at first I had combusted, so thick was the vapour, but the herbs were just a medium to darkish brown with no hot spots or charring (second draw was only whispy). I was still able to function physically but cycling home, I was glad to run on autopilot because I did not recognize where I was at times I still love the combo j-hook and 4-flame torch. I don't get as big clouds or even extraction with a bong or smaller lighters. No combustion has occurred yet, but I also think the j-hook gives you a better sensual feedback than through water.
