invest in some 316le stainless steel wire... it ramps up faster than almost anything ive tried (except nichrome90, which is pretty intense).
as previously mentioned, get good batteries. if your intention is to do super sub ohming i would only trust vtc4s, hb series (hb2, hb4, hb6) or 25r cells for this kind of application. i can personally vouch for vtc4 and hb cells but ive never tried 25r but i know a lot of dudes that do. you can get these at liionwholesale.com for solid price.
i had the apollo its a great device im sure youll enjoy it, just remember to look out for arcing, buffing contacts and negativr ends of cells regularly to avoid buildup and remember to keep the threads clean as itll help maintain good condictivity and will also help with arcing.
dont really want to get into the kind of builds i do as it seems youre a little new to this (no offense, really) but keep in mind these 18650s look small but can explode if not treated with respect, use common sense and learn ohms law. dont try to build super sub owm off the bat try some .3s or .22s first and gain some experience with the device.
thats about all i got at the moment.
