"KeyMonCha", i'm very pleased that you too are finding out what an amazing machine this is. It just keeps on giving and giving.
I've found that less is more when it comes to getting mashed using this godsend of a machine.
Personally, like JFK, i too am a bag man!! ...but i don't know how to spell that in "German"!?!?
I put the bowl in the maghine, add my mini-whip and stick the fan at 3 to heat the whole thing up while a grind up my weed. (This is so painful to type for me right now, as i've no weed and i'm waiting for a guy i know right now to deliver some 'top boot' i'm ashamed to say.

)
My thinking is when i add the weed to the bowl, no more than .2, or .3 of a gram, yes it's one of those "Paddy Power" Ads were you think that can't be right

, but i think with the bag in place, the fan on 3, all that heat is concentrated on vaping your weed, nice and loose to encourage air flow, so none is lost to heating the glass and hench all the goodness possible arrives in the bag, as it's got less chance to condense on any cooler part of the mini-whip.
I start at 195 temp wise and go up as high (pardon the pun!!) as 220. Really i go by the vapour in the bag as to when it's time to set this aside for future use and use some fresh.
As you can probably imagine, when i get my hands on some weed i try and make this go as far as possible, so i don't leave the weed when it's not filling the bag on the machine, or even in the bowl,as i think the heat will vape away some of my hard won goodness.

....so i dump it on to paper until i'm ready to use it again. Typical bloody "Scotsman"!!! just thought i'd get that in before the rest of yous!!!!
I must confess that all this 'good work'?? above in trying to conserve what i have, is massively undone because i love a joint. I mean i, really, really love a joint.

I've never tried packing the weed as you've descrided, as it seems to go against the principle of vaping, but you said it got you mangled, so i'll give that a go the next time i get some herb, ...if the good lord's willing and the creek don't rise....
As "cisco" said, there's always the stuff that builds up which left me in one of the best, or worst, depending on how you look at it!! states i've been in for many a year.
Totally different stone from that given when vaped, started in my belly and rose through my body, amazing stone, so happy, felt like i was 20 again, not 46 grinding years on the planet. Wow, wow, wow.
Annoyingly my toking buddy didn't get the same effect,...although he did say he was pretty high.
I have to say without "bleak" i would not have know about this extra gift, so hats off to the man and all the information you put up for the forum.
"Bleak","Zbeebs","BigRigRob" and others, what advice would you give about my probably misguided attemts to get the best of my vaper?
"TwoCanucks", got some of those bags you recommended so i can finally change my bags

...now all i've got to do is get the bloody things put together!!!
This may something about a friends tolerance, but using the weed i've vaped the life out of, he will be in a state that leaves me 'green' with envy, for many, many hours!!! Lucky bastard.
C'mon the vapers!!
