I have a SL 2X5 Hybrid Pan, back section is 2X3 with drop flues, front section is divided into two and flat bottomed for finishing syrup. My arch is a poorly manufactured homemade oil tank version with a blower, I made it so I know just how bad the build went. I get max 20 gal an hr if my wood is perfect. it takes ALOT of sap to get the continuous flow started but when it does its awesome. I highly recommend SL. Their quality and after purchase service is second to none.
2014 - 6 buckets, 4 coffee cans and a propane burner - almost 40L of sap and 1.6L of syrup
2015 - 103 taps on gravity. Homemade oil tank arch and a Smoky Lake 2' X 5' hybrid. - 2.66 gallons of syrup
2016 - 101 taps, 550 gallons of sap, ~10 gallons of syrup all dark.
2017 - 138 taps, 225 gallons of sap, 5.55 gallons of dark syrup, still procrastinating on the vac.
2018 - ~150 taps, I lost track of the sap it was incredible!, over 20 gal of syrup, all dark.
