Optimal mast height?

My first build has a 29 inch mast. It works but it would be nice to have a bit more ride height in choppy conditions. How tall is too tall? Gong has a 95cm. Is that too much?

At least the gong v1 masts are too flexible for 95cm, it will behave like a noodle…
I have ordered a V2 75cm but haven’t gotten it yet.

I like their 85cm for efoil

I have 95m gong v2. I like it a lot.

The 65 V1 gong got bent… Currently I have the 85 gong V2 and it fits me well.
I am most often in lake or river.
