The Brunswick Karma Urethane is the newest release in the Karma line and it uses a solid urethane cover. The urethane cover comes at a rougher surface than we have seen previously from Brunswick. The combination of the 500/1500 Siaair finish is rough enough to create some traction on medium oily lanes, as long as there is friction to the right.

We had a decent look on our medium pattern playing straighter on the lane. The flare rings were large and noticeable, more so than some other urethane offerings we have tested. As the oil began to carry down the lane, the Karma Urethane started having trouble getting back to the pocket. We moved our target farther left and went with a more direct line
