If you have the money, why not the new Saito FA-82A. It weighs a just a tad bit more than a FA-56, but is lighter than its 65 and 72 brothers. And because it has a .82 displacement, it is more powerful than its 65 and 72 brothers. What extraordinary engineering! My suggestion: if you can stretch your pocket a couple of more bucks, go for the better deal, the Saito FA-82A.
