I found the SC/TO set up exceeded my expectations.
I looked at it for a LOOOOOONG time and dismissed it without investigating.
When I tried bringing my batch size down on my beloved 2# BuzzRoaster drum to 1# it was a
total disaster....
I looked at the SC/TO as just an experiment and that experiment has been lasting over one year now. When this set up burns up I'm getting another. The 12oz batch size is perfect for me and the roast quality/capability is better than I was expecting.
If pressed I'd have to say I prefer the drum first, the HT second, and the SC/TO third but the differences are small and there are trade offs with each roaster that give it +/-
With build yourself set ups you can't go wrong with the SC/TO....you really can't.
