Are those the Efest 1000 mAh? I think their constant discharge rating is 15A. At 0.35 ohms you still have a good safety margin. I use the newest AW 1200 mAh, which has a constant discharge rating of 18A.I have the same dilemma on the 18500 batteries the Reo mini uses. You would be below 10A at 0.5 ohm builds. Around 8.5A. Still a decent vape, but not a 0.2 I'm afraid.
