Don't get to wrapped up with layouts, cover and surface prep are the most important variables. IMHO, it's about getting your ball to slow down so if you can practice on the patterns work with surface prep and make sure you have step downs as the lanes transition. Generally lower diff balls with solid covers are good early but once the lanes transition, cover/core combos that create more angle are needed but still require smoother transitions than we get used to on the THS conditions. Good luck!
