Your post got a bit confusing in the last part. You say the best option to go into LI is through LI K??! or did you mean that the best option when you are IN LI is LI K, or did you mean 6B4G is the best option to go INTO LI, but forgot to state it :)
haha, sorry for being unclear, my bad. i meant after entering LI at advantage from a blocked move the best general option is LI K. so stuff like 6A+B BE>LI on block or 22A>LI on block, in general the best basic option is LI K, since at this point in the game's life most opps are either going to high block or attempt to interrupt, and LI K will beat both of those options (except for very fast interrupts after the 22A>LI transition). i was contrasting that to the use of LI B, which is imo extremely risky because of its slow speed and linearity.
