I had all auto when I first started with the Green Smoke, loved it. Just sent back the GS after receiving my new G6 starter. I ordered it with 1 auto and 1 manual. I now hate using the auto, The manual gives a much hotter hit since you have the control to pre-warm it so to speak. Just ordered 2 more manuals should have em this week. I also have gotten into filling my own mixes and cringe everytime my manual is charging, hope the auto makes till friday.
