You guys know me, the smallest saw I own is 70cc's other than my pole saw. I am always thinking muscle saw, and gravitate toward them. I feel close to perfection between my 2101, and my 660. If you could give and take, what would you want to add? What would you take away, add power? reduce weight? Change the feel? Color whatever, even as small a detail as color or stickers. What would create the ultimate production Muscle saw?
