I too am rocking the orbiter + lotus combo, and I've gotta say, it truly does rock!!! It clouds up like a charm, and the look of the two together is absolutely beautiful- you would think that they were made for each other!!
I've also got an e-nano and mflb that I put through the orbiter, and I've gotta say I think the lotus is my favourite to run through the orbiter because it's the easiest and quickest to get milking!
I want to agree with KidFated on the glass mouthpiece, but so far I havnt tried one. But what I mean is that I don't really like the way a silicone whip can affect the taste (it's not hugely noticeable on the orbiter whips, but it's there), and so I really want to get a straight 14mm glass mouthpiece, but shipping to the UK from underdog (the only place I've found one) is way too expensive.
Quick tip for those with an orbiter AND e-nano (which I discovered a few nights ago):
I was finding it hard to 'milk' the orbiter with the e-nano, and the technique I was trying was your typical 'place nano on gong, draw through whip to fill orbiter, then pull the slide and clear it. What I actually found to be much MUCH better, was leaving the nano on the gong, and just taking long hits from the orbiter, without 'clearing' it. Looking at the orbiter it didn't look like there was much vapour at all, but every draw produced an awesome cloud!! One load produced at least 6 hits like this, and I was truly BAKED!!
