If yixing is not going to improve a shu, well- we will have to resort to more direct means. I'm a big fan of sheng/shu blends like the Dayi 7452 and the uber-cheap Dehong that TeaDB James had fun with. But if you've got lots of shu which didn't get pressed with some token sheng, you can still do your own blending either in the teapot or even in the cup. In the above photo, you will spot one lonely cup of sheng. Actually blog photos can be quite misleading- there's two more supporting teapots and many cups besides this tidy fish plate to get four brews going simultaneously. (Also that yixing gaiwan ended up being a fake yixing but it's a decent gaiwan so I won't start a fight.)
I sometimes keep a sheng brew around to lighten up a shu. Ever since I get my kicks blending hongcha and oolong for my own Russian Caravan I've been more keen to experiment. For me, it's more about enjoying the process rather than unlocking some magic combo. Mostly, a smidgeon of sheng dynamism will make your shu a little lighter and tastier. Just as you won't use the best oolong for Russian Caravan, you can employ so-so shengs into good use.
The sheng pictured above is a Changtai 2006 65th Anniversary Beeng- a pretty decent beeng deserving of being brewed on it's own and no means a beeng which should be relegated to just shu lifting duty. I tend to use whatever sheng I brewed up earlier instead of overthinking the sheng selection as the sheng tends to get drowned out by shu. I've tried mixing the tea leaves but you don't have as much control or flexibility to see how a shu will improve and to determine a working proportion. Also you don't have to have a separate pot for the control brew without the sheng.

One of my favorite runs is on the Berkeley Marina where you have ready views to San Francisco and the Golden Gate Bridge. Early in the year we get green grasses and a profusion of invasive oxalis blooming yellow. But for most of the year, the grass is golden.
When one runs with the bay wind, you can taste the momentary freedom from one's sorrows and burdens. Sometimes when tea does not carry you to the clouds, you have to carry the tea.
