I wanted to thank Jonathan (Jay) Hester and Chris Felts at McCorvey's Pro shop in Lightning Strikes bowling center for the recent work they did for me. I had 2 new balls drilled up a specific way as to benefit me when bowling on the THS (typical house shot) also made a slight change in my grip as to make it more relaxed. Having a relaxed grip so I can use very little pressure to hang on to the ball thus allowing for quick release makes the ball rev more with less effort. It also puts less wear and tear on your hand if you use the proper grip as I have demonstrated on an earlier post. As for the drilling, I haven't bowled on the THS in 3 years except as an occasional sub, so all of my bowling balls were drilled to benefit me on sport bowling conditions. Which to say the least makes me have to work to shoot decent scores on the THS. But now all of that is solved, I am thinking about adding a couple more balls for the THS. Both balls performed as expected using both in 2 league sets so far and rolled a 718 and 696 for 3 games. Don't expect to shoot below 660 now that I have the correct drill pattern for the shot I am shooting on now. So if you need anything done bowling ball wise, these guys are very knowledgeable and get it right the first time.
