Hook tines

So an associate of mine told me about the hook tines that Vermeer is using and I was curious if anyone was running them on there tedders ? Also what there thoughts were on a Vermeer Tedder, I've never owned or operated anything Vermeer made. Secondly is anyone running the wide and thin kits on there new holland mowers ? I just ordered my new nh 312 and the kit to go on it.
