Xiao Jian Zhong tang would have more of a wiry R guan w/ R >L, as the double BS shows up in the pulse. Huang Qi Jian Zhong tang may have a similar pulse (GZ pulse and a Huang Qi Pulse on R guan), but the key would be checking the level of the left guan for a Xu Lao / taxation pulse (comparing R and L guan levels).
