Thanks guys, I think I'm getting a more realistic picture.
Egon, your suggestion of likening the grade to a roof pitch makes sense to me, but confess I still, even after 30 years of working with one, can't confidently say I understand all those chicken scratches on the framing square!
Charlie, GlueGuy, Roy, Slamfire (just how did you get that handle anyway? Are you fond of jalepenos?): Your illustrations are more along the lines of what I was looking for to try and guage what happens, since I am anovice with an absence of significant seat time like you guys. I know it won't be real until I get there, but I'm trying to at least mentally (along with financially) prepare...and guage the import of the right gear, which I at this point I estimate to be firstmost!!
GlueGuy...if you're not inclined to test it over 15 degrees, I'll venture no one is. Thx, you've helped quantify the pucker factor.
Gotta love those duals. eh Charlie? Perhaps your story is the type that inspired Paul Simon to write his song "Slip sliding away"
