This house usually has a little more oil then the previous house for the Black SK but summer time mode is in effect. This video is for 3 of the 4 games I bowled on the fresh and they changed quickly.
It is hard to tell in the video but the Rico drilled ball is smoother then the Red. It has a little more length and a little smoother reaction off the dry.
The Red starts digging in sooner and reacts much stronger to friction. The difference in balls is certainly the layout. Just like the Slingshots were only color variations these are no different.
The hopping is from bowling once every few weeks at best and usually in a hurry. I noticed when I slowed down my feet for this video the balance was a lot better. I still bowled these 4 games as fast as possible because I was running late for other plans I had made.
During the season of bowling it is isn't an issue, and I'm usually lower at the line. Not being up to speed and bowling every few weeks has its effects.
