too lazy reading all the other answers I just give my "routine":
I am a 175 average bowler and so it is difficult for me...
But this is what I once was told by a better bowler:
Take a look what local bowlers do... how do they "attack" the lanes
If there is no time or possibility to see others I just start out 15 and throw over ten with my weakest ball (XXXL) and see how it reacts (practice/warmup session) then I switch to my stronger equipment and even stronger and stronger if needed and get deeper till I am satisfied with carry
and so I try to get a feeling where to send my ball with most room for error and best carry...
(I carry only two reactives and my XXXL... this has to be enough here... after all it is all just THS...
)
