In the article he listed good RDA's for cloud chasing and put an IGO-W as one of the 4.......I had a IGO-W as my first RDA and I don't think I could suggest it for Cloud Chasing, air flow is mediocre and that was after I drilled it out, post holes are tiny, juice well is shallow, idk but I can think of 4 or 5 RDA's that are wayyy better to suggest, I havent read the whole thing but I'm curious now, lol
