You'd be surprised the size of glass that a dynavap can milk up when heated correctly. That's a pretty piece and I honestly recommend you try hitting it dry with the dyna.
On what I'm expecting from the M7; I'm hoping it hits as hard and well as my beloved 2018 SS M. The 2021-ish SS version, as well as the 2019 Ti, were sub par for me. Basically I wanted another SS M, and like the mass I see below the bowl on the M7 tip for heat retention and complete extraction. Otherwise, I'm going into it blind and am curious to see what the M7 has to offer.
As an upcoming accessory maker, I am interested to get calipers on all of the components and note any sizing or design differences between 2018 and now to ensure compatibility.
