In the wind would bet the 12-10 would still outperform the 13-6....

Usually windy conditions mean down in diameter and up in pitch to get some energy and speed.

Glad to see you felt the difference in the way the props can change things.....Those same changes...may not be so profound...but are available in changing minor values like I mentioned the 15-11.5W and the 15-12 and the 15.5-12W......Thats why APC makes all those different sizes.....

Cool Huh?

Thats one thing I have not figured out on the big gas motors and the IMAC guys....most of them haven't learned that props play such a huge role....Look at the selection of props for say a 100cc motor....There are 26-10's and 28-10's and a few others aside from the 3 blades and such..but really in comparison there is quite a limited selection....The biggest selection is different manufacturers rather than different sizes....This work similarly....but it just might be the price of props too...The 26-10's and so on are the $35-60 variety rather than $10-12 on the smaller APC props.....

Glad to you are happy with the prop and the noise issue too....Its kind of cool isn't it?
