I find it can get quite hot depending on what build you use. Recoiled and wicked this afternoon with 24g ni80 claptons, 3mm id and raised a little. This is a must for keeping it running a little cooler, as well as helping flavour. I used to seat my coils lower and it does get very warm and spitty if set up like this.
As to wicking, I think it comes down to what cotton you're using and knowing its performance based on experience.
I generally use fiber freaks, which is essentially idiot proof. Poke it in the holes or rest it on top and it invariably works. Never had a dry hit with it on this tank. If I were using cotton bacon I would avoid poking it down into the holes overmuch, as it wicks much more slowly when compressed.
