Yeah, those Germans sure did try a lot of nutty stuff back then! Not much out of the realm of possiblity with those guys. And that's precisely what makes modeling German gear so much fun!
I haven't seen the Academy links up close, but I've used the ModelKasten Tiger I links, and they are excellent.
Having said that, I'm putting a Friulmodel metal link set together for a Tiger II right now, and they are very very good (and easy to build!).
Anyway, if the ejector pin madness is overwhelming, get either of the AM tracks.
