This guy running the 562xp looks like he watched the video on how to cut quicker cookies by Gypo.

Put a real chain on the 562 and see what it has.

I seen spike got the husqvarna 555 in now.

While I was reading I came across this on the 562xp and 555 comparison. What is the rev-boost that gives short periods of chain speed to the 562xp over the 555 not having it?

The Husqvarna 555 and 562 XP chainsaws boast a sleek and slender product design without sacrificing power.

    * Slimmed-down height and width of the saw chassis makes them easier to handle in almost any application
    * Distance between the front and rear handles has been optimized for efficient, comfortable operation
    * Lowered front handle with an overmold grip
    * Reduced gyro force technology
    * RevBoost (on the 562 XP) allows for acceleration in chain speed over short periods to increase efficiency during cutting, specifically in de-limbing applications

Think I just found my answer.

Available on the 562 XP is the latest breakthrough feature from Husqvarna, Revboost. This feature allows for acceleration in chain speed over short periods to increase efficiency during cutting, specifically in de-limbing applications. Revboost is controlled by the ignition and enables users to increase to maximum RPMs for about two seconds. It is designed to provide an optimum ratio of power to RPMs without having the engine run wide open for extended periods of time. To make field maintenance easier, both new saws come with captive bar nuts that remain attached to the clutch cover. This clever feature reduces the possibility of losing parts and productivity while on the job. In addition to these new developments, the 555 and 562 XP also incorporate many proven elements of Husqvarna’s existing professional-grade chain saws, such as Husqvarna’s X-Torq engine technology, AutoTune technology, LowVib, Smart Start and Air Injection.

2.  another one I was wondering about.

revolutionary reduced gyro force technology. By reducing the weight of the saws’ key moving parts -- fly wheel, crank shaft and piston -- there is less interior movement in the engine, which creates less gyration.

The fack that less rotating mass (weight) results in less gyro effect is just logic - but I can't see what "less movement" means in this context?  ???

I think what they mean Niko by less "movement " is less backward tipping of the saw in the operators hands when throttle is opened to WOT. [The bar nose is more stationary while cutting for better control.]
But I think this would be a disadvantage for some of the old school 6 point limbing technique pros, who relied on the saws inertia movements to make delimbing a tree easier for them with less physical effort and muscle movement.

Honest opinion of the 555 mweba?   Does it weigh in the low 12lb range PHO empty?

The weight "feels" good, wish I had a scale.  The balance on the other hand is great with a 20 and would be fantastic with a 18.

I would you compare 555 to a stock muffler modded 361 for power in the cut and feel of the 361? I never ran a stock 357xp to compare, but used a woods ported one  to drop some poplars and buck to 6-8' logs.

 Compare to a 262xp?  Put it this way I sold my like new 262xp.  ::)

I can't say for sure yet.  Need more run time but I think they have something here.  Add another half horse and a couple more r's and it should be an amazing saw (562).
