I agree, that Tip isn't what I like, so I have a Vince Tip in mine.
I have a 2.5mm 1.4ohm build in mine and it's going beautifully.
@johnnyace .....so you got your corolla in then? How are you finding it compared to the KF3 or Taifun?
I dug out my old KFL today. I coiled it (1 ohm SS), wicked it, stuck some 12mg juice in it and took a vape. Wow. This is still one of the best MTL vapes there is, even after all this time.
