Looks like I am getting atleast two. I have a birthday coming up now, and it looks like I'm getting another Pipeline Pro in another size. I can't praise them enough. Unlike what they say in the reviews, it's really easy to get a Kayfun to sit flush. The Eye looks great too, but it's 23mm. I will wait for the Provari 3.0, watch the reviews and compare their specs.
As for why it is 24w, I don't know. It's a bit on the high side for the 18350 batteries. The AW 18350 has an amp limit of 6.8A, doesn't it? If the battery is running low at around 3.4V, you will push around 6.85V through it at 24W, and that's a bit high. Of course, the 6.8A rating is continuous, so it could be OK to pulse it. Then again, you could have a safety feature making it impossible to hit 24W when the battery is that low. The Eye does have "Amp mode", and that could very well play a part in monitoring the current input, though.
Myself, I rarely use drippers, and I stay in the 9-14W range so I'd be fine either way.
Yeah, 24 Watts would chew through an 18350 pretty quick, if it would fire at all. However, it would be fine for most 650's. The 2.5 goes to 6 volts, which I rarely use, so extra capacity for a broader market just makes perfect sense to me, and the Twist people don't buy Provari's, though they may graduate to them in time, like I did.
