@needalift there is no carb, the resistance is the same for me no matter how long.
I've noticed a difference in performance tho which I can't really explain.
I'm assuming that the longer length accelerates the vapor speed, the longer the stem the more time it has to speed up. It could just be a placebo but I'm not the only one to have noticed.
On the 'grind or not' thing.
I've been 'ripping and stuffing' the last few days.
My regular loads are sucked into the tip but in the name of idleness I've been getting nugs and just stuffing them in.
Not enough to effect the draw but enough that the load feels solid and has not got the give a vacc'd load has.
Like chalk and cheese, the stuffed bowls last much longer and taste better for longer. Empty out shows a lite color in the centre of the nug, crushed up and back in the bowl for another cycle or two.
I get good results and satisfying vapor no matter how I load a bowl.
@Vapor_Eyes I've still to buy a piece of glass to hone that triple 18mm.
This however has given me a run for my money, it's like a joint in that I can put it down and come back to it as and when or you could pass it round friends.
The vapor production is massive.
