I am the same as you. i use 2look OLL and full PLL (except that N!!....N=A+T :p ) but i get good times. i even avg 14 by 2 look. so it all depends on your own but the general advice is: LEARN THEM ALL....
this is a better alg when you want to save other corners....
i use ( R U R' U' 3) when i see two corners not placed in the last layer but when i have only one corner to be placed in the last layer i prefer (R' F R F')
