I checked these out at the Expo yesterday and LF is taking the most realistic route to affordable foils for the masses. This kit also breaks down into a bag for travel, and the LF Kitefish can be finned up and ridden with or without the foil.
They will have replacements parts and upgrade-able fins, so why would I buy a full carbon board for 500-1000 more that is toast after 1 impact? For that kind of money, I'd rather have something durable that I can have fun on without worrying. I would think that with this platform, they will be eventually offering a few fin setups for cruising, performance, etc.
1595 including the board is going to be the price, and they will be available from LF dealers around Christmas time.
On a side note, the new LF bar is really nice too (will be available in a few months). I am looking forward to getting both ASAP.
