Greg, The advertised IBO on the Airborne 101 is 320-328 smooth mods, speed mods come in at 332-340. It seems it should gain at least 8 to 10 fps switching to speed mods. That puts this 101 at a conservative 344 if it had the 30" speed mods installed
At any rate 29" speed mods and it should be hitting at least 336!

Pretty Quick!!
