Chain interchangeability?

[benelli7d]

+2 for replacing the bar with an 18" bar that uses .325"/.050"/72 drive links. All of my 50cc saws use that set-up and the chains are available just about everywhere. Another added bonus is that the saw will like the 18" bar better than the 20" as far as power and cutting speed........

This makes pretty good sense to me and when I wear out my current chains I'm thinking I'll head this way. Thanks
