Looking for a new long, 9,0 or 9,6?

Hello all! i'm new here. i'm looking for a new longboard
9’6” x 22” 1/2 x 3”
Litri: 72,40L[/b]
And a
9’0” x 22” 1/4 x 3”
Litri: 67,90L[/b]
I'm 1:75 cm around 61 kg,
my old long was a 9.0 and I was going to change and go more to a classic style, but I was a little advised against a 9.6 as it is too thin for such a board. I state that I have 6 years of weekly surfing, and honestly I would be more interested in a 9.6 than another 9.0 given the style. Some advice?
