RE: Bowtech Tomkat VS Diamond Liberty
I have shot both bows and would choose the Liberty over the Tomkat. The Liberty, at one point, was Bowtech's flagship bow. It was simply moved to the Diamond lineup because of its single cam design. Speaking of which, they redesigned that single cam again this year to make it a bit faster but just as smooth on the draw.
Two thumbs up for either bow but the Diamond would be my choice.
