I usually give away the Diamond bows after a year, last year I had the BI and ordered a Marquis to be this years hunting bow, I made the mistake of shooting the BI one last time.
Long story short the BI is still here with me I could not part with such a great shooting bow, I know I can set that baby up and shoot lights out with it anytime.
But for now it is nice and cosy in it's case, sitting patiently as my back up.
The Marquis is another great shooting bow and is probably going to stay with me as well.
Best thing to do is go and shoot both then try and decide which one is more suited to you and your shooting style or be like me and have both
