The most frustrating thing about the modern game is that the potential to carry has increased dramatically but the potential to leave 10 pins has also increased. Without getting too much into technical stuff, the entry angles have increased during the resin ball era, even for lower rev players. The result is more half pocket hits that have burned just enough to leave weak 10s. I have shot more than a handful of 300s where I only shot a little 700 even though I hit the pocket consistently for 3 games. Not just bad luck, but also not much I could do about it.
