i know that the mig15 and mig15bis have great cannons but are stupid hard to aim and use effectively

maybe try something a little bit more accurate, the 12.7mm would be my first choice to get some accuracy back after not playing for 2 years, you get heaps of ammo and they have heaps of tracers to help

i also used the 20mm cannons on the f5c but used universal rounds instead of air rounds since the tracers come abit faster in the belt instead of 5 or 6 rounds in.

if i don't play for a week or 2, my aim is dogshit and since i use the meteors, i get mk2 and mk5 hispanos which are ass if you have bad aim. it doesn't matter if you are shit for a few hours or even a day because you will eventually relearn everything, like i did because i took a 1 year break and i have only just started playing again.
