Re: Nour vs. KM
I also have both (full disclosure: I have 1 Nour, 3 other Syrians, and 5 KM's). For this purpose I'll compare the Nour with a KM Dual Tone. Here's my $0.02:
Look: Both are beautiful pipes, but I'd give the edge to the Nour
Construction: Nour is much heavier, sturdier than the KM. Advantage Nour
Pull: Both have great pull (I'm lucky), however I'll give the nod to the KM
Other: You'll likely get a better hose with the KM. I also find with all of my Syrian's that the vase grommets suck. I've had to MacGyver mine up, otherwise the vase will fall off if I pick up the hookah by the stem. KM takes this category
Overall: If money is no object, I'd say buy both. However, if pressed I have to declare KM the winner.
