Ha ha - hmmmmmmmm I used to work with Trifolio (7 yrs ago now). Personally I wouldn't use him - never been keen on his temper/character. I know he has been successful - esp. recently, but that would not change my mind. That is just my opinion though.
alleycat, if you were considering teofilo but were put off by his temperment , have a look at Endoli hes a nice sort . sire of advanced eventers apache sauce and beckli.
Know nothing about him other than seeing a stunning liver chestnut filly by him in the 2y.o class at Pavo last autumn, I'm 99% sure she was in the top three of her class and had taken a few championships previously. Going against the grain she was very sweet and laidback so maybe her dam had an especially good temp!
