As for SD-2s, try angles 30/31/32 and find it your self, since everyone is lying about 32GA... Forget about miniznis, unless your gunners are low lvl.

Golden angle on SD-2 is 30. I don't use mini-zini so I don't know.

SD-2 is 30-31 and minizinis is 36

SD-2 is 31-32 and minizinis is 36

SD2 golden angle = 30 Minizini golden angle = 36 but I prefer to use SD2

mizzini have better reload than sd2.

SD-2's are stronger and go a bit further'' one shot planes''. i was lvling with the Minizini, and they were fine for me, but at stalingrad, the sd-2's are where its at. i think the minizini's are weigh less, could help with speed. i tested the angles and MInizini's were shooting planes down at 36, and SD-2's at 31,golden angle.
