Last night was the first night of my summer Sport Condition
league.  It's 12 weeks, 3 patterns in a 4 week block.  The
first is oil to 38 feet.  It will get progressively shorter
from what I heard.

I'm looking at getting a dryer condition ball and looking
the Track Hex, Columbia Wild R/G/R right now with a 5x5
drilling.  I have had good success with Track pearls in the
past so I'm kinda partial to the Hex.  Any other suggestions?

I'm most likely a tweener, with a track close to my thumb
hole, average revs, and 15-17 mph ball speed.  

Thanks.

I can't speak on the shorter sport type oil patterns, but after bowling on a 42' sport pattern for the last two seasons this is what I've experienced and maybe this can be helpful.

First off I don't think looking for a condition specific ball is the best way to go because on a sport condition, accuracy a free arm swing and consistant release are key.

I've managed over the last two seasons to maintain a 180 average using Lane#1 equipment i.e a silver diamond drilled label leverage when the condition is fresh and changing to an XL drilled on axis as the shot transisions.

Both of these balls are pearl reactives, which is kind of contrary to what others have been suggesting is ideal. I know averaging 180 is not that impressive but take into account that this season I've averaged 180 for the 4 game league  sets without shooting one series over 800.

This goes back to accuracy and consistancy being key.
