As for the GenSan-CDO corridor, would say most traffic will pass thru Kidapawan instead of bypassing it, and for the Bukidnon segment, consider Sayre as the main route (the route via Talakag is fairly remote, would keep primary for the route there as an less favorable alternative). As for Davao-Valencia, not sure, but I would assign one trunk route only (maybe most traffic would pass via Maramag, but would check DPWH traffic data if that holds true).
