I guess at some point you'll just have to "trust us" when we (Joe,
Steve, Loic, and myself) say that Talons are well made and a good fit
for our hobby.
Besides, if you're really worried about operating them continuously at
60A, then you should follow the manufacturer's advice and attach a
standard CPU fan to the heat sink using the provided mount points. The
efficiency of the heat sink is significantly improved with such a fan
attached and it only costs a couple bucks.

FET absolute maximum current rating is not the point here. Of course
they are rated for over 60 amps. Theres a key difference between
transient and continuous loading.
The issue is that those same fets derate rapidly with heat; you might
get 160+ amps at 20 degrees, but it goes down very fast as they get hot,
which in turn happens very fast if you have a small heat sink like the
Talons do. At 40 amps none of this is an issue; at 60 the small heatsink
is a concern and at 100 its a fatal flaw.
