"It's still unproven atm and that's the problem"

How much proof is needed ? An engineering report on the COretrack site seems to indicate it has better pull back than it was desighed for plus it has completed at least one contract with an abnormally large diameter bit.
To me that vindicates its design if not its reliability,

I think its more that operators need to prove they know how to operate the rig with the ancillaries and Kelley needs to prove he can get at least 80% utilisation from it with decent margins, ( thinking a minimum $35,000 gross per day to achieve that drilling for oil.).
