Hey FC,Recently bought a Solo as my first vaporizer (which I love and have already quit combustion including smoking cigs) - I'm all for vaporizing now, and a lot of my friends are seeing the benefits as well.However, we all have a very high tolerance, and when we each need two bowls on 7 out of a water tool, it shows that the Solo really is just that, a solo device (which it does wonderfully i might add).So I need another one - One for parties and sessions where we are several people (anywhere from 2 to 10) that need to get high off of it. When we visit coffeeshops in Amsterdam a lot of them have a few volcanos set up. And while we like them, they are not "good" enough for getting 10 people high. I'm sure they are good, but the whole bag-delivery system doesn't work for us. I don't know if it's because of THC condensating on the inside, or what the reason is, but we are not getting high (enough), unless I - like on the solo - refill all the time, which I would prefer not to. Right now I fill a solo bowl, turn it on 7, let it pre-heat and use a big normal bong to fill up the chamber and then inhale that at once. It seems to give the best head-rush and combustion-like high (without the combustion negatives). However, as i said we need at least 1-2 of these each, so it does take a while - and without a PA on the solo I really have to stay on top of the battery to make sure it doesn't run out.So - is there a vape out there for us? And what is the best delivery-method? Bag, whip or into a piece of glass as we are doing now?
