I am going to ask the question ...where do you want to fit it into your quiver and on what do you want ride it?
I to am very similar size to you ..same height, smidgen lighter (91kg) and ride both shorties of similar volume and longboards.
Whilst being a relative newcomer to the many years of sage advice on this forum, ..... is the board for grovel days, big flowing point breaks, to be a wave hoare (not that there anything wrong with that

), or ...?
I have a 9'3 x 23 x 2.75 that is my bigger longboard and allrounder and also a 9'1 x 22.5 x 2.5 that is my more performance longboard. What I find is I am not riding the 9'3 as most of the time I want a LB is when it it really small ..so more log style would suit. I do ride my 9'1 on big days and long points
The question you need to ask is....what do you want the board for ...then decide on size ...thats my thoughts, but I am new to this
