Hi jivebuggered,
When I got my PNWT the only vendor that would ship to Oz was theyoyokid. Certainly Vapor Blunt wasn't shipping here and I think that's still the case. Postage was steep at $30 but the price of the tube + postage will still come out the same or cheaper than the F-Bomb. I love the PNWT. The draw on it is beautiful and light. It actually feels to me like it lowers the resistence coming from the stem, although I'm not sure how that's possible.
Technically,water reduces the amount of goodies that get to your lungs. Practically, you will probably get stronger effects. Most of us can draw longer and take bigger hits with water and can also take those hits closer together and this gives stronger effects than a larger amount of material consumed over even a slightly longer time.
Flavor isn't diminished much at all from the little bit of water in the PNWT. Level 3 with water tastes much better than level 4 dry and I find that the effects I get from 3 with water are satisfying, whereas if I'm vaping dry I need to go to 4 to get the same kick.
If you've got your heart set on a PNWT, I would wait for it to come back into stock at theyoyokid1. Otherwise I'm sure you would be happy with an F-Bomb.
If you don't need a straight water tube there is the Black Leaf inline diffuser at PV for $70 or $80. There is also another Black Leaf one around the same price that @
ataxian uses. This one takes an 18mm GonG though.
There is one more option for hydrating your vapour. Thermovape have a moisture conditioner called the Smooth-Flow. I have one and I can insert it into the mouthpiece end of the Solo stem (it may not fit in every stem. It fits in my straight stock stem and my straight PVHES, but not my bent stock stem). This does a great job of taking the harshness off the vapour. You can get one of these from Thermovape or from Australian Vaporizers.
Planet Vape is the only place to get their GonG's apart from somewhere in England. Shipping from PV is cheap. Watch it though. Sometimes it's cheaper to post 2 items separately rather than together. If you buy 2 GonG's it will cost you $10 or $20. It's definitely $10 for one.
You asked about the orientation of the solo in water pipes. The Solo can be used on any angle without any problems. Have you been using it upside down like a rat feeder tube?
Hope this helps you out.
Cheers
