Approaches are fine, a little slick at Ledgeview.

I pulled off 1850 scratch, but it was a frustrating weekend.

My first game of each set was always under 190 which didn't help my brackets, so I lost money there.  On the other hand, my second game was never under 250. 

The lanes didn't seem too ridiculous, but Ledgeview didn't seem to transition until the middle of game 5 for me.

Seemed like for Team the people that could throw it straighter did a little better. You had very little miss room inside, but some to the outside. Team was my worst event, of course always thinking back, I wish I would have played more outside and straighter. Dbls./Singles seemed like a more playable version of Team, little more wiggle room each way.
Good luck!

For those who have went, is there any need for a "dry" lane ball or is there enough volume that this hole could be filled with something else?

Thanks.

Depends on your ability to get deeper in singles and team as the lanes transition and heads start to go.  I always tend to stay with stronger equipment as they dry out ie. for me a Motiv Thrash Frenzy was my ball of choice.  Real dry lanes equipment for myself wasn't needed but that's because of my technique and ability to move in.  I always think generally of bowlers that use dry lane equipment as those that like to stay further outside and play straighter trajectories and don't have the ability to move in to see skid, hook, roll.

I'm not sure if it was me or the pair we were on, or what.  The lanes never seemed to transition for me.  I barely moved in (less than 5 boards) by game six of singles and doubles.  It was actually quite annoying.  I've never played so straight for so many games.

Team didn't open up nearly as much as I though it would on the old wood.

This was very true for me as well. Again, I guess it would depend on who your bowling with and the pair you were on. For Team we were on 1 & 2, probably not the best scoring pair in the house. But at both places I didn't move a whole lot and we even had 2 other Lefty's on our pairs. My best ball was my Rising Star. I played fairly straight at both places but scored better in Dbls./Singles. Had very bad carry at Karl Ray, pins were sliding on the decks. It was good spare practice though. :-)

Anyone care to share equipment ?
symmetric or asymmetric?
pin up or down?
surface?

holy crap!!

I read this earlier and bass will know most if not all of these guys.  I know one of the companion team bowlers Jerry Brotz.  When you are used to rolling on old wood like T&O you'd be right at home at Karl Ray.  I'd suppose they drew a decent pair.

Hit them just right! Congrats! That will be tough to beat if not impossible.
