TM2 or Pax for vaping hash

Title says it all. I have a TM2 and a Pax Plus. Generally I use the Pax for hash, but I prefer the TM2 in general. Anyone try it with hash? I would sandwich it in with AVB. How long do you have to puff on the thing before you've extracted the hash? Is it just 3 or 4 long pulls like with flower or are you at it a while? Thanks!
