Having missed on the HR, I've been looking through the photographs of Busses here on the forum, and my heart stopped when I noticed SHSH. I then understood why I'd missed on the HR - it's because my real love was still waiting for me. 
Anyway, I've RTFMed and searched, and I understand some early SHSH II had A2 steel instead of INFI, but I am still not clear on the differences between the SHSH and SHSH II. Any kind soul can help me with the differences?
