Michael, it seems every time you help someone out, you expand my knowledge about the subject. The Riptide comments you volunteered explained some of the how and why of Riptide that no other source has provided. Also, no fragmented odds and ends from you; you always provide the full explanation. You are a one and only. Thanks again.

BTW. If you could harvest the nuggets you, and others, have provided here it would make one hell of a manual or six. Coming from you, the manual would certainly be more useful than most.
