I have the 140l 6'9" Gong Zuma 2022, I think the 2023 boards are the same shape. For winging I found the board very stable at rest (it's a big board) but also very slow to get going. It is a wide board and the bottom shape doesn't help IMHO. The smaller shapes are also wide for their length.
Mine is mostly used for SUP Foil where it works OK but paddles like a slug. So for my 2 cents its up there for stability but if you want early flying something slightly narrower would be good. The AFS has been on my radar for a while but I have only tried the old Fire which was a good board.
