Two boards would definitely be ideal.
If one board, 122 definitely a magic size for big boys going hard over chop, and in most conditions would be a good choice for 105kg rider in 20-25kts.
Problem will be how bad is the chop, because in many cases with solid 25-30 kts in open water, the chop is really getting bad, and in this case, a smaller board may still offer the better choice (or less demanding) ride.
2 board quiver 133+ 111(115) would be certainly give a better overall range/solution.
