Looking for some input for oil pattern for tournament I run. This is my 10th year doing it and I always put out a Kegel Challenge pattern and have used all the navigational patterns. I don't bowl many tournaments currently so I am not out traveling every weekend like some on here. I like the Challenge patterns because I want all to be able to compete. The tournament is a State Mixed Doubles wit scratch and handicap division and I do not want the 235 average chasing others away and that is why I have always chosen a Challenge pattern. We will be bowling on 1 year old Brunswick HPL's. Was looking at Chichen Itza. Looking for a scorable pattern, but not a strike fest.

They are Brunswick Pro Lane. They were put in last fall.

The modern game favors higher rev players in general, but longer patterns only favor high rev players with low axis rotation, rather than the stand left throw right crowd.  As a low rev guy myself my best luck is on either very short patterns or very long patterns.  It is the 39-42 foot patterns that I often struggle with.  Short patterns are probably toughest on high rev players, but they also hurt a lot of seniors and women. 

It is very difficult to find a truly neutral pattern with respect to all styles and ability levels.  I agree that probably a 40 foot pattern with some OB gives the most styles a chance. 

It really gets down to styles.  At some level lane patterns don't really have much impact.  A lot of higher average women probably would struggle on a 3-1 pattern.  I read the original request to be addressing a concern about the power playing crowd coming in and posting telephone numbers.  If you start getting over 4-1 at 40 feet, it is surprising how big the scores can get.
