The Talon UL is the best Talon.
1. I've got the whole set, and with 20m lines 20 DaN I almost never misses a SUL. (But I've not flown a Nirvana UL.)
2. Almost the same! For some tricks a bit more slack is needed (Backspincascade) and Slotmachines or Multislots are a bit easier.
(3. There is also het Vented: also the same inputs all around.)
