Want to change my Drivers shaft

Hey guys, I'm new to the forum so excuse me if I'm doing anything wrong.

I play a Callaway XR 16 Regular flex standard shaft 45.75" FUJIKURA SPEEDER 565 EVOLUTION (excuse caps, i copy/pasted)

I'm finding the shaft is just too long for me. I've measured my wrist to floor and I'm at 33inch. What would be the ideal length shaft I should look for, and by look I mean just ebay item descriptions.

Or am I going about this all wrong?

Thanks guys!
