@Ted S Understood! Thank you very much for the response. I know that having a headache-free layout means having an enjoyable layout. I'll use the scenery elevation changes to give the illusion. I'm sure less elevation will help with longevity as well.
I sincerely appreciate all that have taken time to share their experience and insight. I can't believe how much the plan has evolved... and for the better!!
I'm definitely in your debt. THANK YOU!
