I shot some of nearly every bow available at the show in Wheeling, WV this year, in hopes of finding my first LB to begin my Trad journey. At the end of the day I shot each of Abe's designs... thinking they were too expensive, but I wanted to try them.
His silverfox is as good a 3-piece as you can get... if you can afford it. While I liked his Snowbird and Peregrine... he had a Featherhorn that felt like magic to me. So much so, I busted my budget on the spot and have been shooting it like a madman ever since.
Generally, Featherhorn is less R/D, slower but more forgiving and nothing smoother.
Peregrine is more R/D, very fast-high performance, but perhaps not as forgiving.
I would say Snowbird is something in between.
You can't go wrong... just choose by what qualities you value most. If you are a speed-freak... the Peregrine is your bow. If you want smooth and forgiving... I have to recommend the Featherhorn.
