bowler0821, you have what looks to me like a darn sweet arsenal already. Remember last year how they oiled.
Woodland - 42"
Expo - 39"
Western - 36"
I would bet that this year the patterns will be similar, modified sport shot, With speed and hand adjustments Your arsenal should pretty much cover anything you will see.
Strike Zone: Heavy oil ball
Paradigm: Medium-Heavy oil
Road Hawg: Medium
Mojo: Medium that will handle oil carry down
Screamin Banshee Light oil
Ice: Light to dry
Blue Dot: Spares
The Overtime would be a nice ball to have but I don't see where you have a glaring gap.
Just my thoughts, Tom
