I've popped a few coils using the pulse method with 30 gauge however that's all I have at the moment do to a serious lack of funds. Hopefully I'll be able to pick up some 28 gauge soon. Takes alot of finessing to get the 30 gauge to work right on my aga t 2 due to those thumb screws always over tightening my coil creating a top coil hot spot. However I finally got a build to work but it's a little too high in resistance for my taste.
