The Merlin's are my choice also. I'm shooting a Max2000, duel cam @62lbs w/27.5" draw. I'm getting 280 fps w/carbon select arrows. My arrow is 26"@ 4.5 gr.per lb. The draw cycle on there duel cam is smooth and solid with a draw stop. I have the composite limbs. I think you might get little more speed from the new carbon limbs. You have to shoot it to appreciate it. JERRY
