I just switched to 15lb. strike balls 9 months
ago, but still carried my 16lb. White Dot for
spares. Found that I was suddenly having trouble
covering 10 Pins. Spoke to my Pro Shop guy about
going to a 14lb spare ball.He told me some guys
may have problems covering spares going 1 pound
lighter.Some guys don't.I found a 14lb. White Dot
on Ebay cheap.So I had it drilled up and tried it.
I love it. It's easier to throw and I'm more accurate
with,compared to the 16lb. White Dot. Being lighter,
throwing at your normal strike ball speed should be fine.
I say try it!
