i bowl 2 handed as well and over the year ive been bowling 2 handed, ive learned it isnt about the ball brand. Its about the layout on the ball.

I'm a 2 hander throwing dv8 mostly, a neon misfit pearl has become my favorite ball for house shots recently. Everything else I throw on my medium oil house shot over reacts or I have to keep moving in every few frames

Diva or Marauder Mutiny

Surface can always be changed later, but chances are he knows what will work best in the house, just make sure you explain to him your style and how you like to play the lanes ie track area, get deep and swing it, or keep it a little straighter

My bro is a 2 hander and I will agree that it is not the brand so much as it is the layouts.  However, DV8 offers a number of symmetric balls with predictable enough shapes for a high rev, high track player to be successful.
Like most 2 handers track very high due to such a strong wrist position, so he worries about tracking over the fingers/thumb hole with pin downs and pins too far from the axis.
His go to balls are currently a blue Karma and Versa, but has had success with the Reckless, Too Reckless and Diva as they provide him the most forgiveness and smooth angles on the lane.  All 5 balls I listed are symmetric and the only ball that is not a solid is the Reckless which is fairly early for a pearl.  He bowls primarily on house conditions, and likes 4-5" pins with a drilling angle of about 45 degrees matte finishes to light polish.

Just an update, I ended up going with the Marauder Mutiny.. Definitely feels like the right choice. It didn't over hook once, and left some room for error even if I missed my mark by 3-4 boards. Ended up with a 213-146-207 when I usually only average about a 145.
