Feedback above about not covering a lot of boards is spot on. I learned to bowl outside of house shots in Bay Division (Nor Cal)ABT years ago, before PBA ex leagues, named animal patterns designed to increase/challenge skill, etc.
For years this division never laid anything close to a house shot. When we would show up at Nationals, everyone thought the division was a bunch of baggers due to playing on these conditions, then walking into a house shot. This was years ago back in the Showboat days
I used to have have good results with a midnight scorcher back in the day
while many players of higher ability struggled trying to "find area". The key was traction thru the oil (getting the ball to hit), a straighter trajectory and I'll admit the the design of the ball did give me more room then most, though not a ton of room.
If you truly want a Visionary for this condition, try to find a discontinued Centaur AMB Particle. For super flat and long patterns this ball works extremely well and will offer a more room then many other balls. This ball can still be found on the internet.
That being said it will probably stay in your bag for every other condition as it truly is a speciality heavy oil ball
