Project X Catalyst 55 5.0 - shaft type?

It doesn't appear this forum gets much traffic, so hopefully someone can answer my question. 

Just bought a pre-owned Mavrik Max 21 degree hybrid online. I've slowed down a bit in my 50's, so I'm down to a regular shaft. The club came w/ the above mentioned Project X Catalyst 55 5.0 shaft. I purchased a regular flex, but just it seems much lighter and "loose" when I wiggled it back and forth (in the house, never out in public 😉). I could not find any information about this shaft. I did see something vaguely that it might be a senior flex...but was unsure if that was the same shaft. 

Any help would be appreciated. Thanks.

If you read the specs for the catalyst shaft, the 55 gram shaft is considered a "light" flex which would probably equate to a senior flex.  The 65 gram is regular and 75 gram is still.  https://www.callawaygolfpreowned.com/hybrids/hybrids-2020-mavrik-max.html.    55 grams is generally considered pretty lightweight for a hybrid shaft which is probably why it feels so light.

I am a certified fitter for Callaway and to answer your question the 5.0 refers to a senior flex shaft. Normally golfers with a driver club head speed between 75 to 85 mph need a senior flex. Good luck.
