Benjamin/Henderson put together a pump book, and a few people BITCHED about it. Jack put together a better book, and FEW [user name] people are BITCHING about it. HELL somebody put the Bible in writing centuries ago, and WE are still BITCHING about it.
It is easier to BITCH about somebody else's work than to keep their mouth shut, or use REAL NAMES in their postings.
Besides, Jack looks more like Santa Claus in shorts.
