can someone give me shaft characteristics of a Crazy shaft, model is S- 531b prototype Stiff flex. research here shows initial product writeup is that it will handle quicker, faster swings and offers penetrating flight, while other posts say it plays fairly soft with a softer tip. any other clarification you can help? ss is up to 100 with moderate acceleration and release.

Before Royal Deco and Prototype lines Crazy played stiff to flex. The S-531b Proto stiff is MUCH softer than the corresponding original. 6.9 - "stiff" arround 25 cpm!

Stiff but and tip soft, mid launch with a lot of roll.

It's more a distance kind of shaft.

thanks. currently have one but wasn't sure of characteristics. seems to work fine, but wonder if the soft tip could cause too much spin?

I have a prototype 519 stiff if you want to try that one

thanks, but that would likely be for someone more aggressive than me. just ordered a cobra fly z that i will put the 531 in

This Proto is the prototype of the royal decoration which is why it plays soft.

Most Crazy shafts play to flex or stiffer it just depends on the shaft profile you select.
