I am selling my 7m and 9m CORE GTS6 with core sensor 3pro bar!! The 7m is practically brand new, I pumped it no more than 3 times.. 9m has been used a couple of dozen times along the year. No much wind unfortunately. I always used the kite with 22 meters lines to make it more responsive, I don't know where I stored the 2m extensions, Easy to order online if you need them. I paid last year over $5300.00 for this set. I am selling everything for $3500.00. Just washed them and ready to go :)
