if this tournament is important for u, go with something u know very well instead of something that u have no idea.
as balls, a good fit and right surface on any brand new high performance ball will do the job
--------------------
When a house bowler misses the mark, misses the break point and strike, for many ppl its called a wallshot. When a pro does that its call adjustment
When a house bowler gets his finger stuck in the ball and fall on the lanes, for many ppl its called lame bowler. When a pro does that its called the Machuga flop! ha i like this one.
