Speed....yes it is the former CR.
Sim01.....I know the man you are maligning, and believe me he has vast experience and his integrity and standards are impeccable. If in fact he is being investigated, I am sure HKCAD will be impressed by what they find.
The 2 other friends I have there would not compromise their reputations either. As I am in regular contact with them, and have heard nothing of the problems you allege, perhaps it would be best to await the outcome of the HKCAD investigation.
