Since you asked, as if my preference should matter in the slightest to your selection of features for your custom stock...

I wouldn't have any checkering at all. The grip would be contoured for my hand and left smooth.

The forend would also be shaped for my thumb and pointy finger.

What could be better? Checkering serves no useful purpose on target guns and just chews your hands up.

If someone else didn't like it, they could just kiss my heinie.

Sorry for being so callous. As you pointed out, it's my nature.
