You forgot to add "for me" because just as no two people are built exactly alike, you cannot with a straight face say that what fits one man to a "T" will fit the next man the same way.
Nothing works like that, not cars seats nor rifle stocks, pistol grips, etc...
And that, my friends, is why there are different brands of saws and even Dolmar and Husqvarna make many different models of similar 50cc saws
