Never shot the martin, Im sure they are good bows I just dont care for them. I just got my Cardiac last week and I can honestly say it is by far the best bow I have owned to date. Ive shot Browning, Darton, Mathews, Bowtech, Hoyt and in my opinion Ross has them all beat with the new cardiac. If you want a super smooth, fast, almost dead silent bow then check one out.
