Bill, this guy is not a tech diver. He has no buisiness diving beyond recreational limits, and that is why my advise to him would end there. Granted a 30cuft pony would be insufficient at 140 and beyond, it will be plenty of gas to get you safely to the surface on a 130' dive as long as you have no DECO obligation, which he should not have anyway. Im fairly positive he's not going to be diving wrecks in the tech range, especially with the way the boat operators are screening divers nowadays.
