I know there are way better heads to match up to hobbit for better cooling but I’m really in budget mode right now and have two 39mm puch heads I can rip into. The one on the left has a squish band but smaller fins. Looks like it might be easier to slot the holes too. The one on the right has larger fins but no band and the slotting might get tricky with those raised tabs? Out of the two, which would you choose?
Full disclosure, I’m running a DR, proma, boison stock reeds, and vm20.
Also, shoutout to JBOT for the good puch head matching thread from a while back. Had a lot of good info in that thread.
