How about considering the type of grip as well? There is a huge variety of grips out there. Problem is finding the bar/grip combo which is closest to optimal.

For me, decades of riding give insight and intuition towards my solutions.

I like to to ride rigid bikes a lot on single track, and so the grip choice is paramount. The mushroom style grip is one of the most forgiving.

Ergo grips offer excellent relief, but the downside is that they are less easy to hold on to when things get really hectic. But if you don't push the envelope or ride technical trails, I'd say look into them.

There's nothing wrong with not riding like you stole it all the time.

Another thing to try is various grip thickness.

Also road bar tape actually can make a decent mountain bike grip believe it or not, and there are gel pads that can be placed under the tape as well.

There are even grips that have a small bit of suspension travel in them. I haven't tried them, but the concept has merit IMHO.
