Talbot would have been better, but since they already made him out of Ross, if the Red Hulk remains I say leave him Thunderbolt rather than an even lamer switcheroo after the fact. If Marvel felt the need for an amoral Hulk they could have just brought back the Gray/Fixit persona. If an equally-powerful opponent was merely the goal they shouldn't have killed off the original Blonsky Abomination.
