That may be true. I'll have to give yours a shot before I make the decision, but it seems (with exceptions) that I've always been better served by buying a tool that's a bit more robust than what was actually req'd for the task at hand. The tools seem to live longer when they're not taxed as heavily. I could get by w/a 1/2 ton truck, but my 350 Super Duty has had the frame and mass to handle large loads much better, same goes for the MS660 vs 039 in larger hardwoods. BUT, if the less expensive, lesser powered engine will get it done, then I'm all for it. I guess I need to bring some accurate test pieces w/me and give yous a trial run @ the GTG if you don't mind.
