Nice thread. I ended up going with the 20 ton black widow with low temp 4x7 plates just like Aero's. It's turning into a cool hobby when I got time, and makes good use of the little buds and trim.
At first I was using Raw parchment paper and getting the gooey resin off sucked. Putting it in the freezer helped, but it was still shitty paper. Also, on hard presses over 10 ton, the oil/resin would go right through the raw paper and end up on the plates.
I switched to the 10x10'' pre cut oil slick paper and it was smooth sailing . Big difference in the work load, the resin pulled right off, even the goo, and does not go through the paper anymore.
I pressed some older hash and got about 50+% return through 37 bags but consistency was brittle /shatter. That one I had to pull off paper right away when it is still warm before it dries brittle and flies all over the place.
It definitely takes some getting used to to get a knack for it, very temp dependent ...
I'm gonna try the low temp seamless 220 bags for flower next and see how that goes...
