interesting that you didn't like red code. outlast has similar playability as pro red code. great control string as well except it has more power and pop as well as increased spin. i get more action on the ball and the ball jumps up off the court more w/ red code.
regarding comfort level of Outlast. it depends on tension and racquet. i string it in btwn 48-50#s. when i had it in my Yonex RDS001 MP which has a 68RA flex rating, it did bother my shoulder but in my Vantage BC20 which has a 49RA flex rating, it's fine.
