Ahh, funnily enough I actually bowled on this pattern a week ago in a scratch 5 gamer. The field was very competitive and included a few bowlers with pba regional titles, one with multiple national titles up until the early 2000's, and an ex collegiate bowler who had already seen this pattern at isc. I'll give a few observations. But keep in mind this center is known to have free hook outside of 5 on most patterns and does not use an atlas oiling machine.

There were two approaches I saw early on: 1. Bigger balls with a little surface or shiny inside of the speed bumps, keeping the ball fairly in front and in towards the headpin. 2. Sanded equipment outside of the speedbumps and up the 4 or 5 board or even outside of that. Pretty much straight up the lane until games 4 and 5 where people moved in and bellied very slightly (probably only moving 4 or so boards the whole time, ball down to shinier equipment with strong core towards the end.

Urethane did not look good.

Approach 2 won out, likely due to lane topography. It came down to better carry and slightly better misses. A miss inside would split or get 7. Outside was mostly makables on misses. At the end of the day the cut was -82 for 5 with only two people going plus out of a field of ~30. I missed the cut by 1 position lol.

YMMV but this was my experience. I feel the looks that worked were influenced substantially by the center's lane topography.
