When my stuff was late to Nationals in Reno this year, I had to buy new equipment. Got a great deal at the L/LM booth on a Big R Bang, Big Bang, and Arrow for a spare ball.
Used the Big Bang for all 9 games at Nationals and was very pleased. More oil and a longer pattern this year and the Big Bang (Pin below Ring, CG kicked out) gave me a hard arc recovery without over reaction, even in doubles and singles where in past tournaments I have had to pull my dryest lane stuff out to cope with the big back ends.
This year in league it is in my bag every night but (late league) we haven't had enough oil so I have used the Big R Bang ( 4 x 4, pin above ring) almost exclusively and it has worked great. However, in practice sessions at a house with more oil I have the same reaction as at Reno. I feel good that with medium to medium/heavy oil conditions I will have the right ball. Not for really heavy though.
