Hell, I've considered moving down to 14 as I still ping too many 9 pins with my 15lb stuff. It's a matter or preference, but, for me, the strength and hitting power built into today's gear leaves little to no need to throw 16. I think the only exception is maybe in terms of light oil gear that doesn't flare. For anything that hooks, however, 15 hits just as hard and tends to give better deflection. That's my experience, anyhow.
