CONN-FERR ALL THE WAY. I bought the OPW (one piece weld) full length (6' long by 4'6") wide with the gutter mount brackets = SOLID, SOLID, SOLID. I am a property insurance adjuster and use the rack to travel across the country with the rack packed full with all my gear and use it daily for a ladder rack. No problems except yes, it does show some small signs of rust where I have scraped off the powder coat finish with my ladder. I did a lot of research on rack and my choice was the same as yours: Conn-ferr vs. Wilderness rack. Both showed similar strength qualities but I chose the Conn-ferr simply because it looks better than the Wilderness rack. I think I paid $700 for the rack, mounting brackets, and shipping to Indiana from CA, not cheap but worth it in the long haul = totally satisfied.
