EDM & Fowler,

Thank you both for shareing you insightful discoveries!
I'm printing this information, and slipping it into the pages
of "Shooting Flying" as an addendum!
It appears you two could sit down together and carry on
a long conversation,that would be very insightful if
one could listen in. Thanks again. Best regards. R Rambler
