Maybe my approach created a failsafe. I snugged up Ties in the valley areas, not tight enough to cut the hose on the ridges, but snug enough that the hose could not expand over the ridge areas on the fitting. Dunno. Just seemed like a logical fail safe to me. I'll be pulling the lower cover this week to do my first change since the install (3500 miles) and will report back if there is any hose creep...
More than a few have installed this very set-up with no issues..
