Pros: it improves sound quality when used in conjunction with a decent amp
Cons: could either be lower profile and have a snap in, button release like the l3
it is simple it does exactly what it was designed to do and nothing else. the build however is incredible. i held it up to the l1 my freind has and the difference in the quality and size of cable etc is night and day. if you need a LOD it is great for portable rigs but doesn't do anything other LODs do, it just seems like it will outlast your needs for it.
