Agree with the above poster.
I have set the 3pt tendency in my sliders at 90.
But you nearly need to give up the 3pt shot in order for them to shoot it regularly.
Just played a game against GSW where I packed the paint and gave them the 3pt shot and they actually shot 14 on 6min qtrs so it is possible.
The downside was they hit about 9 of them.....
