Gong Karmen 8'9" 140 litres.
Smik Hipster Twin 8'6" 134 litres.
For my weight at 65kgs (add board, paddle and wetsuit and call it 75kgs) a Guild factor of 1.5 would be 112 litres. In the Spicey
A Karmen 8'9" would be way oversized for 65 kg!
In the Karmen line, for 110 liters this means the Karmen 7'11"
And you even have 3 smaller Karmens in the line.
But you were saying you wanted glide. Thus you want a longboard shape, something with a fast rocker.
The Karmen is a shortboard shape, with more rocker. Getting a Karmen (or any shortboard shape, in any brand), too big for your weight will not provide you glide (it will have even more rocker, and be wider), it will just make it unnecessarily heavy and hard to turn.
If you want glide, get a shape with glide, but properly sized to your weight.
For instance you want a NFA 9'0" XS (110L) or 8'5" (100L), or the Zero 9'0" (115L) or 8'5" (100L)
The 8'5" longboard SUPs are especially nice: suprizing glide, but still able to tackle Hossegor hollow waves.
