Hope I helped. Best of luck with your build as well.
Do you experience any done with your Super turbos? Don't remember if you said they did. I'm really thing I may do the Super Turbos with the cut outs and bullets on those.
I may leave it like it is for awhile too. I'm going to get a YouTube started it too. I'm pretty sure ill go with bullets, maybe buy al three and swap what I want that specific day.
