He probably does, possibly depending on the engine, but getting him to answer email is so impossible he may as well be on the dark side of the moon. He likes phone calls, but I've gone so deaf that it's a pain in the ass. Besides, what's wrong with email? I'd definitely go for another of his engines. I have use for a pair of T4s. But first I need to get to the bottom of this one, and since he's not responding, I'm looking to work with someone else on this one. Time is precious to me, too!
