Greetings..
I spent 12 years in the Wah Lum system and the instructor, Harry Lo, is an excellent and knowledgable teacher. They have a good student base and excellent assistants.. and, you are very close to Wah Lum's headquarters and G'Master Chan Pui.. as BeiTangLang said, go there for the answers.. opinions here can be prejudiced by many factors.. there was much about the system i found to be superior, and some things deficient.. like all things, Yin AND Yang.
Be well..
