Requesting tactical help for LaGG-3

[Flanker1985]

Hi, guys. I just want to ask how can I go against BF-109s with LaGG-3. I use to fly MiG-3 in the earlier war, but that was before the 4.11. And now I don't have enough manuverability to dodge 109's fire when I have my radiator open. So I have to turn to LaGG-3 (since I fly Lavochkin in the middle and later wars).
But the thing is LaGG-3 had no speed nor energy MiGs have. 109 can always run away if they want to, and everytime I lose the chase because they climb, since I don't have the speed to catch them. The worsest part is their shoot and run tactics, they climb very high above me and dive to shoot me, if I do the defensive manuver, I will lost so much speed and I couldn't catch them after they finish their attack dive. And that would give them the opportunity to climb very high above me and do it again. And if I don't do the defensive manuver, I will most likely end up being shot down.

If you are an experience pilot and have some solutions, please help.
