I think their lightly oxidized teas are fantastic - better than anything I've had from some of the other well known tea vendors - for that style. I'd recommend their Ten Wu - over the years it's my favorite tea. It's available in various grades. The better grades are a bit more smooth/fragrant, but even their mid grades are very good.
