Possibly a daft question, but what does the MkII signify?
MkII is grading, yes, and a big jump in price points.  We have only ever stocked the MkIIs because the MkIs are a tad overpriced in my book.  Also, having seen, and compared, both grades up close and personal, there really isn't that much to choose between them.
Thanks for posting this, Hima.  I appreciate your patience, too! I'm delighted, and relieved, that you finally got your kit - FEDEX have never grilled me so much, I can tell you!  You must indeed be a very aggressive batsman!
