One of the better things to do that will help the best is maybe get a couple very smooth rolling balls, and perhaps even a high load particle ball so it will blend the lane as good as possible.
One of the balls that everyone talks about is a cell of course. Get that one and another high load particle ball, and you wont have so much over/under sideways movement on the backend. I personally like my Big Bangs on the tougher conditions. They are highly polished and skid great with a smooth backend transition. Other than that, I would really stay away from pearl balls because a majority of shots will be harder to play when you have a ball thats has alot of energy in the back.
Along with the spare shooting as well of course, and a great point( bigcountry). Thats what makes the best of the best is the spares. Also good to have a dull ball to produce a burn rate. Hope this helps, John
