I need to apologize to Spectre at this point.
On 10/26 he posted a reply to this thread which was responded to by Kodiac and fal308 the next day. As I was on "duty" here those two days, it could only have been me who deleted his post. (I was cleaning up double posts at the time.)
For those of you who noticed and wondered if we'd censored the post, the answer is "no". For those of us who missed Spectre's input, which is invariably worthwhile, I offer my sincere apologies.
To Spectre, of course my apology. I'd personally appreciate a repost either here or by email.
