Ok got a proper b rod together and these are my thoughts, it stinks! The restriction from the balls isn't as good as the carb cap. And maybe it was bad luck but I seemed to only have poor airflow on half the bowl?!? Because every time I hit it when I'd remove the heater everything was mounded up on one side of the bowl? All my hits were whispy without the cap! Maybe if I shake and shimmy I might randomly knock the balls into a better position with more even heating but frankly when I used the 4,mm balls I got better results and that still wasn't very good either. I even managed to spill a couple hot balls
I'm sure with a little tweaking I might improve to mediocre
but at my temp I saw no improvement with the balls to density or longevity to my hits, with or without cap! I didn't like it, the e elev8r is the superior ball vape vs the b rod
Edit keep her stock gentleman!
