I've been trying to get in touch with someone from tech about bow selection between the Hunter and Mamba. I'm sitting right around a 28'' draw and am concerned about stacking. I've also gotten mixed reviews as to limb length/cast of these 2 bows. Is the hunter riser longer than that of the mamba with longer limbs? Shorter riser with longer limbs etc? These are some concerns of mine. I spoke with another distributer who was trying to sell me the mamba because he felt it would have greater cast due to its shorter limbs. I've spoken to others with the opposite opinion. I've contacted Martin archery tech line on numerous occasions but have been unable to speak with someone in person. Any information/help would be greatly appreciated.
