I dropped to 14lb before last year and I love the lighter weight! I'm also a senior bowler and you won't regret the change. I've scored really well with the Oath, Mass Eruption and Violent Eruption in the Columbia line. I love the Track 508A and I have a fairly strong drilling on it and can use it on most conditions. I have some Hammer balls that will be here this week that I'm excited to drill. The Amp, Absolute Curve, Spike and Nail Titanium. You may see your stats change when you drop ball weight so have ball speed, pap, and revs checked once you change. Just let me know how I can help in any way, Bruce
