I guess that using the term Boom&Zoom could be misleading for a green 109 pilot. Usually the B&Z is associated with the FW, F4U, P47 ... style.
This is not the case with the 109, which is much better for a Hit&Run and Hit&Climb combat styles. I mean, the 109G-K should attack from level or very shallow dive. This way you can avoid compression and use the acceleration and climb abilities of the 109s to get a "window" exit from the fight. Moreover, you avoid to dive under the horizontal plane of the prey and loose E without reason.
