Vandy Vape also do spools of various MTL Clapton and Fused Clapton wires that are worth a look (the Superfine range). I have used MTL wires from Vandy and Coilology and find them equally good.
Personally I wouldn't worry too much about aiming for 1 ohm resistance unless you are using a mech mod, I've found going lower or higher makes little difference in practice.
A 6 wrap 2.5mm i.d. Vandy SS316L 32x2/38 Fused Clapton will come out around 1.03 Ohms
If you want to stick with Kanthal -
A 6 wrap 2.5mm i.d. Vandy KA1 30x2/38 Fused Clapton will be in the 0.80 ohm ballpark.
You don't HAVE to use a set power level for a set resistance, I think that school of thought is from the days where your only choice was battery output only and you had to build to narrow resistance margins to get a suitable vape. I think the 'you have to vape this resistance at this power school' of thought isn't relevant with complex MTL wires (I've vaped a 0.40 ohm Coilology MTL Staple coil at 15 Watts and got a great vape from it). Just my personal opinion, but I think going higher or lower with your builds makes zero difference when you can adjust the power and airflow and complex MTL wires ARE better than round-wire, Not a massive improvement, but still an improvement.
Edit - Complex MTL wires ARE better... unless you have a tank that you have to wrap wires around screws - then you're stuck with round-wire.
