what is it like riding with 3 fins

What do you guys think its like riding with three fins on each end. One 6" x 0.75" center fin and two 9" x 0.75 outer fins

Locked in, very locked in.

Finless is the way to go

24" of fin on each end DOES seem a bit like overkill

It really depends on where you're at in your progression. IMO, fins are great for learning how to jump the wake with proper body position. I personally found it helpful to start with more fins, then reduce over time to get a more playful and forgiving feel.

All preference. Some of the pro riders also prefer a board with a lot of fin. It's not just for beginners.

I despise boards that lock in tight to the water, but that's just me.
