I've had a Herbalaire fpr 6 months now, but there is something about it I haven't been happy about. In fact, I rarely use it. I have a chest condition, therefore lung power is limited, and I find the draw on the Herbalaire too tight for me - it really is hard work, and this puts me off using it. Also, it doesn't give me the stone I'm looking for. I know you can't get a couch-lock stone from a vapourizer, but I'd like the next best thing, if possible. So I am looking to get something that is easy to draw on, gives me a physical aspect to the stone, but hopefully, is as efficient as the Herbalaire. It should also be able to be used upside down with a 18mm bowl bong - hopefully without any extra attachments necessary. From what I can gather on these forums, it looks like my options are the Cloud/EVO or the LSV. So, I would appreciate any thoughts, advice or alternatives other members can offer. Thanks in advance.
