Coil build for Protank2 on 3.7 Mech Mod Help.

Yes I need a good coil build for a Protank2 and Sigelei 19 with 18650 Sony VTC5. At the moment I only have 31 gauge kanthal.

Reason for question.
Put a 1.2 ohm on MVP2 VV 4.2 no problem. Same 1.2 on Sigelei 19 and get cotton burn hits at end of draw.
What to do with what I have?
