Vaping at 260watts sounds absolutely ridiculous. My computer runs off of 200 watts, my laptop even less! I vape at 11.1 watts and get decent vapor and good flavor, if I'm feeling really zaney I'll vape at 20 watts and take 1 second hits. Carrielsal I like that post it's so true, wattage isn't the only factor in blowing big clouds.
Anyways, get a mod that you want. The nice thing about a high wattage mod is you CAN use higher power if you want too. However, no one uses that much power, it's absolutely ridiculous. Basically getting a 100W mod is already beyond the limit of what you would use imo. In a recent poll (
http://www.e-cigarette-forum.com/forum/polls/635240-how-many-watts-do-you-vape.html), 80% of people vape from 3-25 watts. 16% from 25-60watts. 4% from 60-100 watts. No surprise here, 0% of the people vaped at 100-260w.
I prefer 18650 batteries but everyone is different.
