luv,
I always use the higher ohm to get a cooler vape. 2.6ohm doesn't suit me as I've experienced the same things as you have. Try the higher ohm. Also, I take mine apart to fill it. The ceramic cup cap is a little bit of a pain to get out but it can be done. After removing it, I take cuticle scissors and clip the wick openings a little bit bigger. Helps wick my juice faster so I never encounter burnt flavors.
