I love how Krusty still thinks he is AH's aircraft expert when he keeps getting proven wrong.
P38L at 50% is good for 20 minutes and a little over 40 minutes for 100%
As for ammo, I only watch my cannon rounds. I start with 150 20mm cannon roundss and often have 5+ kills before I reach the 100 cannon mark.
I like the P38L and think the J is overrated, some say the J turns better but I've not been outmanouvered by a J yet in my L. I prefer the J and L over the G because the J and L fit me better. G turns too well for my taste, I like angles.
There really are 2 kinds of fighters in AH, BnZ crowd and TnB crowd. For each crowd there are certain planes which are generalized for that group. I saw it as a hierarchy, you start off in fm2s, hurricanes and zeros, moved to spits, then to more challenging TnB fighters such as F4U, P40, 109 for some, P51 for some. I saw (my personal opinion) the P38 as the top of the ladder for TnB because it is a big plane that requires much patients to master.
Maybe it is just how long I have been flying the P38, but it doesn't feel any bigger to me than a 109.
As for the P38 attracting enemies, it is true, and I like it. "I would rather be fought over than fight with friendlies for an assist"
I think the P38 has sniper like gunnery in comparison with wing mounted planes. Not long ago a spit16 was following shuffler up in a climb, the spit16 was at the point where it completely lost all momentum and was just about to start falling backwards, I took it's wingroot off 1k out.
