I'm a soft tonno guy myself. I don't need fort knox security and rolling it up in seconds w/o having to remove anything is great. I also prefer the sort of domed look a soft tonno gives rather than the flat look. That's just me.
I think I like the Undercover better. Plus my old Bak leaked pretty bad because it sat beside the rails and not over them. If I was getting a hard tonneau, then I would want it to be pretty water tight.
In any case, there do not appear to be any hard tonneau's available yet for the LWB Titans.
