Help with arsenal and strategy

[Ticker]

I am joined a scratch league that is the best in town. They are goign to switch the shot from week to week from a sport shot to pba patterns etc. We will never know what pattern and we will have to adjust to the length/volume etc. My question is how can I make the transition as easy as possible? I am expecting to get hammered by the better bowlers and I want to get better and I feel this is the best way by bowling on tougher conditions. Any advice on strategy or arsenal changes>
Thanks
