RE: bigger and heavier
My wind planes are a SIG Kougar and SIG King Kobra. 40 and 60 size planes. These are NOT ARF's. They are tough, durable and can handle the wind. I have two Kougars one electric and one with a 45 Rossi I won't hesitate to put them up in the wind. I also have a small old style pattern plane called the GNAT converted to electric it flies good in the wind too. It has less than a 40 inch wingspan and weights less than 2 lbs with battery.
The people saying lean more toward pattern style are correct they will be more stable in most conditions. They penetrate the wind well. Most are trike gear which gives them better ground handling in the wind too.
A decathalon in a firm wind might act like a kite depending on the airfoil. The Kaos 40 as suggested earlier might be a decent choice if you are an arf'r.
