Cheers for replies guys
For info it was future fins. Dont think it really matters what brand of board,fin,kite etc with accidents i always feel it comes with the territory injuries and extreme sports. You have to prepared to take them now and again and try all you can to minimise the risk.
Just come back from hopsital check, apparently i lacerated the vastus lateralis which aint bad going as fin went in the back and thats more round the front of the leg
and severe brusing of t everything especially the nerves which is why the bottom of my leg feels like someone elses.
I count my self lucky really could have been far worse if it was inches up down or sidewards.
Now to recover so can hit the water soon via a nice relaxing holiday to errrr Disney world and universal for 2weeks via a nice long haul flight from UK
Also Really gutted as managed to get some decent height on a couple of strapless airs at the start of the session and now need to go backwards to go forwards
