"you are way ahead of me" is not the term that comes to my mind as I have gone into the RHS site and just got bogged down, which is why I was looking for your help. Sometimes after you show me (us) the way, I can root around and find additional info. Again thanks.
With regard to the RHS site, I think this is one of their shortfalls to not include these variations or at least link this info in some way or maybe they do I just don't know how to find it.
