Looking for a DHV upgrade...

Would you recommend using the glass WPA as a regular mouth piece instead of the stock?

The stock mouthpiece cools better and is more discreet but the glass MP/WPA feels familiar and orientated directly above the oven, an almost all glass vapor path that delivers better flavour IMO as vapor is not being robbed by the cooling process.

For OnDemand, would you suggest the glass or SS chamber? (Would using caps matter?)

I prefer glass if I use the on-demand. I rarely use it in on-demand mode due to just getting both wrists Carpal Tunnel released plus I find 5 clicks on, wait for ready vibration, puff and 5 click off towards the end of my toke to preserve the herb for another hit later if mobile works for me.

.would those other mesh screens just be a third party screen?

I use the included spare disc as a template to make my own with mesh and scissors if I cannot find my DDave Dynavap Ti screens as these rarely ever need deep cleaning.

VapCap Mesh Screen Replacements

VapCaps are great-working vaporizers! And just like any other vaporizer, they work best when clean.Finally! An economical option for VapCap screens!These screens replace the internally-installed VapCap screens with your choice of 316 Stainless Steel or Titanium mesh screens. Both the SS and Ti...

Correct me if I'm wrong, but it sounds as if the glass chamber is better in session for loose bud while the SS chamber is better for the caps?

That is what I and others prefer, but your use could be different; all good to try.

Can I mix hash with a bowl?

I have done but only inverted on a j-hook using the Roffu like a cordless log on a TWAX (rosin topped dry herb)

Is it better with course or fine ground bud or does it matter?

Medium seems great, I use a medium plate BCG or my Old Mate Aroma3.
You are welcome to ask more questions in the Roffu thread to get more answers/opinions than just mine if you like.
Also, our quick swap battery is the best (most fun) I have used,

I prefer the glass chamber, fwiw. Possibly worth buying a few spares as mine cracked after a couple of days. The replacement has been fine though so it may have been a faulty unit. When I had to wait for the replacement to arrive, I really did miss having the roffu around, even though I'd only had it for a couple of days prior.

I use a fine-ish grind. I tend to remove the glass chamber to empty (blow down the other end) and fill (scoop it through the 'erb and tamp it very lightly with my finger).

My preference is for the stock mouthpiece. I bought the WPA after hearing it was much better, but I don't notice much difference and the device looks better and is easier to carry with the standard mouthpiece. If you're familiar with a pax mouthpiece, it's basically that.

Just tried mixing hash with a bowl for the first time last night - worked a treat. Swapping the battery is not the most fun I've ever had, but it sure is nice and easy. I'm hoping that hinge doesn't break over time.

I hope you get plenty of good vapes out of it... sure you will
