I havn't messed with the butane, I like alcohal extractions at home, but I would love to use CO2 if I ever get serious. I also have a glass nail so not worried about the titanium to much. When I was at the cup man all the oil, shatter, and wax was very flavorful. Lots of pine flavors, some strong lemon, and orange flavors form some, a couple that tasted like cleaner but not really in a bad way if that makes sense.
