I put this machine through its paces today for the 1st time. I'm glad I did as I was having doubts about its value. I own a David Future Line selectorized pullover, which I like. This machine out performed the David in pre stretch and is equal in the strength curve for a complete contraction of the back. A+ plate loaded pullover. Hammer Strength cannot begin to compare to the Rom and the feel of the contraction from this great Avenger piece!
