I think that you will find some great opinions here. Speaking for most of the Ambassadors, I believe that we are generally ICON fans - some more than others. Fortunately, we all have experience with different FJ styles, so you are in the right place. Personally, I would go with the ICON's - I think they are the best shoe available. I have walked 36 without any issues.
The most important thing is to be fitted. Don't spend your money on a pair that you think will fit right. Make sure you are properly sized before you buy. Also, wear the same type of socks that you would wear on the course for your fitting...it makes a difference.
