Whether or not it's worth for you is hard to say. But one factor you should consider when looking to invest in a tank is whether or not you can get the coils for it easily or at all. That's an older tank. About 2016-ish. I do see that Fasttech (china)
still sells the BF/Cubis coils to it may be worth it. Careful, FT sells clones of this coil. If the title doesn't start with "Joyetech", it's likely a clone.
As far as MTL, that tank will do a loose MTL and either the 1.0 or 1.5 clapton is what you'd bee looking to use. The 1.5 clapton might produce better flavor. depending on your juice and wattage.
