If you are thinking 9'2 Flow:
I will say, there is a world of difference when talking 9'2 Flow.
At 8'10 the Flow is a performance board ... but IMO when you cross the line to the 9'2 it becomes a great
intermediate board.
I had to hold back on frontside turns on the 9'2, but can easily lay down the 8'10 into a hard turn.
The 9'2 is super stable, picks up waves easily, turns easily from the middle and is fast.
It just doesn't go on rail as easy as the smaller Flows... so not as high performance.
That makes the 9'2 Flow, the perfect choice for an intermediate who is looking to go shorter.
I wish I could comment on the 9'1 Creek, but I haven't gotten mine yet.
I am guessing the stability will be similar to the 8'10 Flow.....
But I have paddled the 8'10 Creek... it is not as stable as the 8'10 Flow.
My 9'4 Creek is super stable, but each size down is a fairly big step.
The 9'1 should be perfect for me right now., but I'm getting smaller.... 8'10 by summer????

I'm going to repost my "Stability Test" video here, because it shows direct comps to the 8'10 Flow, 9'2 Speeed, 9'2 Skate, 9'4 Creek, 9'4 Acid.
They may seem like dissimilar sizes..... but the results may surprise you.
I strapped on my "Kook Hat Cam" and just said what came out.
No plan.... just an honest evaluation of every board's stability.... and anything else that came out.
