Yeah it seems like more has been getting sucked into the pipe as well. I did like the extra surface area of the pearls, but i have to see if the 6 or 8 is making more of a mess. I think I might be able to knock 30F or more off my controller temp with pearls because of how much faster the extraction is.
I did a deep clean today, to remove all reclaim from the Tbucket/cap. My first session with 2x8mm Ruby pearls was surprisingly clean. Was previously running 530F (Auber) , this session was 500F and I still feel like I have room to move downward.
