AArrg!

3 replies and still no answer to the question, dang it!

Yes Gary, I should have said camber and not hump. I must have camels on the brain today or I'm just getting old, sorry.

It's nice to know that I'm not the only one who finds this worthy of question.

If anybody can come up with the answer, I'd really appreciate it.

Thanks,

Ren
