I've used 32 and 30 ga kanthal A-1. I prefer 30 ga.

7-8 wraps around a 5/64th drill bit gives around 2 ohms. 32 ga will give a little higher, closer to 2.5. But you could also wrap around a 1/16 drill bit to bring the resistance down a bit, but I like to keep my coils around 1.8-2.0 ohms for my devices.

You can squeeze in a coil with 28 ga kanthal, but it's a tight fit.
