The SlingShot Wing Raider would be good safe choice at 4'8" x 26" @ 80 Liters.
I have the 4'10" 90Liters and at around body weight it is very comfortable board in comparison
to other boards I tried ( including the Fanatic & Cabrinha ).
The board has huge adjustment range with 14" boxes and reduced nose volume makes it
really nimble even at 90 Liters. Wetted surface of the board is ridiculously low, it will
release and pop-up like a much smaller board.
That said, for my lower volume board I am actually looking at the F-One range.
I believe these thin boards move better through the water and more direct feel of the foil.
I think think the F-One has a better volume distribution than the SlingShot ( and the Cabrinha)
and it is easier to pump the board out of the water. I mostly use F-One foils and with the SlingShot
that means I have to shim the base plate or ride slightly nose down.
As mentioned, the F-One boards are very light and thin and with its lower volume, rocker tail 5'x 23" x 3.7" x 60L
you'll be standing roughly 1" closer to the foil in comparison to the Cabrinha Macro 4'8" x23 x 3.9" x 58L board.
Thinking out loud, I'll take the 1" thinner and 4" longer of similar weight board.
