Hi,
I just wanted to let you know the outcome. I had spoken with North and they sent a new 2012 iron heart the same day I had spoken with them (plus another surprise part which I don't want to mention or everybody would contact them, hoping for that part). The holes of the 2013 iron heart are different to the one from the micro-hook. If I would drill new holes to fit the micro-hook, they would result in long holes and that would not function.
That's what I call great customer service!
I'm still waiting for a functioning QR from Epic (and this since July last year!) since their QR failed when I needed to deploy it last year. I was dragged on the beach for more than 100 meters while I tried to release that piece of junk with all my forces, resulting in 1 night in hospital, 6 weeks out of the water and a write-off of that kite which ended up in a tree and saved me from more injuries or killing me (read the article of that Canadian kiter who just died in a similar accident). Several local kiters saw the accident and how I desperately tried to release the QR (in case you Epic followers/supporters question that or come up with 'my QR is working fine'). Several other Epic kite owners I contacted said the same that it is very hard to deploy that QR.
No sign of a replacement kite or 2 functioning replacement Quick Releases (I have another 10m LTD, 9m and the other QR of that kite is doing exactly the same).
Cheers
Caesar
