No idea. There are a few tell tale signs in the various generations. Very first ones had a slightly different logo, the early USA made ones had the deck and bottom skins finishing further back so more of the perimeter balsa was on show, then when RF was introduced the FST boards had an F infront of the model name on the rail, then FCS fusion plugs were introduced, then ventless models, now you have the top FST logo as well as the bottom.
Do you know the years as I think the little bit of fading and design differences really make it easy to tell the differences. I was just wondering from the production side if their was a certain number that made firewire transition. I love their boards and will keep riding them as long as I can.
Do you think there were like 6-10k boards made before the switch over to the newer style with the vent. As I know that 2010-present are the ventless boards.
sorry, I am not following your question. What are you curious about? We don't build boards to a certain number then make the change, rather we come across ideas for running changes and make them if we feel they can make the boards perform or look better without sacrificing anything...
