I would say that sounds just about right..........Allegiance, Switchback, and whatever Hoyt's comparable bow is.
From what I am hearing about the Allegiance and Defender is that they are extremely recoil and noise free. One guy said that the Allegiance was quieter than his Liberty which is saying something. [:-]They are Rockets too.
WWAG's Allegiance came in at 317fps for a 29"/ 60# model with a full string load.
I know I will be shooting an Allegiance for hunting this year but at my 30" draw length I'm just going to get a 60# model myself. With that kind of speed I don't need to bother with 70#. I should get around 300fps with my 400gr hunting arrows out of a 60#'r which is almost silly.
