L rolls better at low and high speeds than the J which helps tremendously. A lot of the guys who use the L as purely for attack sorties are highly underestimating the ability of the aircraft in air to air engagements. She's just like the J except she rolls much better and that makes the difference in a dogfight.
I fly the L exclusively since I'm a former 190 stick and utilizing the roll rate to out maneuver bandits was a must since you couldn't use pure turning maneuvers.
