my $.02 worth
the 550 is awesome. Is it really more powerful than a modern 60cc saw? Of course not. Would it give it a run for its money in that size wood? It just did, and beat it. This was more of a demonstration than a "test" with certain advantages going to the 550. We were on a very tight time schedule so a more "fair" comparison could not happen. That being said, this saw is breaking new ground. With this technology and performance it's quickly closing the 10cc gap. Soon enough, the ultimate one saw plan won't be a 60cc, it'll be a 50 cc saw. It's not quite there just yet, but soon. All the neighsayers can gripe, kick, scream and whine all they want, but this is the beginning of the end for the old technology The 550 is the new darling and it should be, it's got everything going for it.
