the best thing you can do to be successful on these tougher patterns is to understand more about layouts, ball surfaces and lane play.
And as mentioned above, practice, practice spares, be able to throw a straight ball at all spares (minus double wood)
for me, the improvements i chose to make were 1st with my fundamentals, although i had success on THS, that did not transition well enough to these patterns.
I am always working on having sound fundamentals and the rest falls into place a little easier
