Sub-ohm coil longevity on the isub v APEX tank

[Ironsharpensiron]

So I upgraded and got the new Cool Fire IV TC 100w sub-ohm 3300mah. I'm currently using the BVC Clapton coil for the isub v tank I've been exsperimenting with it, and one coil only lasted me three days, when I've heard people say their coil lasts them two weeks. Is it the coil, is it junk, should I go with a nickel 200, or titanium, or the Stainless steel coil. What is the best coil that lasts the longest, For the isub v apex tank?

A few things... What setting are you vaping at and you VG to PG ratio in your juice?

I have the iSub Apex (not the V) and I use the BVC claptons. My coils do indeed last 2+ weeks and I throw all different kinds of juices in it at 70-80vg. I vape at 55-60 watts. Don't use the temp setting with those coils. Sometimes though you do get a dud coil, it happens.
