This is a frequently asked, and loaded, question, that's given way to the frequent, and loaded, responses. If you're use to playing with a Predator, you'll find the Schon deflects like crazy. If you're willing to change over & re-learn accordingly - then go for it. I've used LD shafts for years, and I don't agree with all the bad press that they're hooey, just as so many others - including tons of top pros - don't agree. It's what YOU play well with. I shot with a real nice Schon for a long time. Used pre-cat 314 shafts on it. I wouldn't have walked across the room to pick up a Schon shaft to play with - and I bought 2 with my cue. WAY too much deflection for me.
I'll tell you this story...
When I bought my Schon, Predator was still in the US, and was inundated with shaft orders from the Far East. Back order was approx 8 weeks.
I ordered 2 314's thru Hawley's in Texas because they had an order in the pipe. Here's the kicker... They'd even sold ALL of their 314 shafts off of their in stock Predator cue butts, and Hawley told me himself that the biggest percentage of Predator shafts were being purchased by people to use on Schon cues.
Today I don't recommend Predator shafts, but I do still use LD shafts. I'm just not an LD shaft snob. It's what you get accustomed to. That's the only real truth.
