Thanks Collin, I appreciate the time you took to put together this post. Being a low time pilot, I am prone to gross mistatement of the "facts" at times. This condition will improve over time and through discussions like this one.
Everyting you've said here makes perfect sense and dovetails nicely with what I've been taught regarding flying. Thanks again ...
