Well

All depends on how often this cable might break though. What's gonna be more expensive? 1 (say) 6 inch diameter cable once a year, or several 2 inch diameter cables each year?
Then, of course, you've got the downtime. Not sure what that's like in your line of work, but where I come from downtime costs more money than anything, both in loss of earnings, paying employees for doing nothing and through repairing the error that caused the downtime in the first place...
