Hey guys, I am a 190-200 average bowler depending on the year. I have been throwing a No Rules Pearl since like 2017. USBC sanctioned league and I don't bowl much outside of it. Our house has been changing oil patterns and quantities quite a bit this year so my average is down about ten pins due to inconsistency . Mostly a tweener but sometimes a stroker if the oil is heavy. Every so often when the lanes break down I move left and use more of the lane. I'm 35, I don't have a big arm so certainly not throwing high revs. I have always just used one ball at all times (I know, I need a spare ball but I've got quite used to ten pins with my NR Pearl). I had the pro shop clean the ball up last year but maybe I need to do that again?

Any recommendations for a complimentary ball? I want something different for those nights when I just can't seem to figure it out with the NR Pearl.

Edit: Forgot to mention, I throw a 15lb ball
