Hi Steveo
At 95kg you Guild factors on the SP25
8'8 x 31.3 @ 138 L ----Guild Factor = 1.48
8'11 x 32.25 @ 150 L --Guild Factor = 1.61
I have 3 SP25's
8'11 x 32.25 @ 150 L ---- my weight when I got it 102kg ----- G/F = 1.47
8'8 x 31.3 @ 138 l ---- weight now 98kg ----- G/F = 1.41
Also
I rode a 9'5 while at the GenRation SUP Retreat in Punta Mita, Mexico
It was so easy and fun that I ordered one, just to have around for the super wonky or wetsuit days
9'5 x 34 @ 177 L ------ G/F = off the charts

at 1.8
My 8'11 is super stable and probably the board that I surf best.
I love it so much that I got the 8'8 because there really is a lot of difference at each size, and I really want to see what I can do on the smaller board.
My 8'8 is quite a bit smaller than my 8'11 and looks/feels totally amazing.
Here is a picture of my buddy who is a 91kg rider with his new 8'8 SP25
He reported that it was comfortable in some wonk in a full wetsuit.
He is blown away how well it surfs and how fast it is.
He's a very good surfer.

Both my cars are broken down at the moment and all my SUPs are in my Cargo trailer 10 miles away, so I can't get any side by side pics of my 8'11 and 8'8 until I am mobil again.
As soon as I am mobil again I will do a paddle/stability comparison and post here.
Here's a video that shows how nicely my 8'11 surfs
