Re: big hoses vs little hoses
Well, i think that everyone else has beat this into the ground, but I'll throw my words of wisdom (see: stupidity) in here:
Larger hoses like Nammor, Razan, Grand, and KM hoses are wider gauged, meaning they can amass larger quantities of smoke in a single pull. Think about drinking from a drinking straw as opposed to drinking a widemouth bottle.
It's been said that the smaller hoses do a have a tighter draw, which is correct. The smaller hoses are for people that like a little resistance, so they feel like they aren't sucking in just air.
