Yeah, that's a possibility.. the whole thing will need to be tested so I'll have to wait and see how it pans out.
I've already had 5 of the bars made up by UKNeil and I'm just waiting for the new carrier plates to come back from the printers. I'm hoping they'll be with me early next week with some luck, then I just need to give them a test to see if they're strong enough.
It'll take a while to get it right but once it's right then churning them out in larger numbers isn't a problem.
A no hassle drop in replacement hook for an EV2 Mk4 and FTP would be a really useful accessory I reckon. The difference in stability in all positions between the standard AA hooks and my hook is going to be something you'll notice instantly.
