Sunset Beach and San O Surfer

Hi all,
I’m brand new to the forum and looking forward to some tips and feedback from here on out. I’ve been surfing for just about 10 months, consistently, and have a wavestorm, 7’8” Jacks Surfboard and just picked up a 9’0” Robert August “What I Ride” for a steal. I tried to take out the big center fin earlier and when I put it back in, I noticed it was very loose towards the front. It was tighter towards the back, but still wiggly. Is that how it should be?
