Hardy and others - thank you MUCHO Beaucoup!  All replies were filled with sound suggestions or anecdotal evidence that have helped me put together a trade study that is leading me to.....erect a horizontal loop (making it as long on the sides as possible) and look into running as long a BOG as I can.  Between them I outta figure out if one is "worth more" than the other or, keep both and figure out a simple switching method between 'em.

Certainly received more information and positive suggestions than I anticipated.  Subject is closed, from my perspective, as I've got 'work to do"  Hi Hi
